Jonczyk Company is considering two different, mutually exclusive capital expenditure proposals. Project A will cost $454,000, has an expected useful life of 13 years and a salvage value of zero, and is expected to increase net annual cash flows by $68,000. Project B will cost $300,000, has an expected useful life of 13 years and a salvage value of zero, and is expected to increase net annual cash flows by $47,000. A discount rate of 9% is appropriate for both projects. Click here to view PV table.
Calculate the net present value and profitability index of each project. (If the net present value is negative, use either a negative sign preceding the number e.g. -45 or parentheses e.g. (45). Round present value answers to 0 decimal places, e.g. 125 and profitability index answers to 2 decimal places, e.g. 15.52. For calculation purposes, use 5 decimal places as displayed in the factor table provided, e.g. 1.25124.)
Answers
Net present value is a measure of profitability. The NPV of an investment is the net cash inflow received over the project's life, less the initial cash outflow, adjusted for the time value of money.
A higher NPV means the project is more lucrative. The profitability index measures the benefit-cost ratio of a project and is calculated by dividing the present value of future cash flows by the initial cash outflow. A profitability index greater than one indicates that the project will be profitable, whereas a profitability index less than one indicates that the project will not be profitable.

The graph below shows a company’s profit f(x) in dollars depending on the price of pens x, in dollars, sold by the company What do the x-intercepts and maximum value of the graph represent? What are the intervals where the function is increasing and decreasing and what do they represent about the sale and profit? What is an aproxímate average rate of change of the graph from x=3 to x=5 and what does this rate represent?
Answers
Solution:
Given:
\(\begin{gathered} f(x)=profits \\ x=price\text{ of pens} \end{gathered}\)From the graph, the x-intercept exists at (0,0) and (6,0).
The maximum value is (3,120).
The x-intercept represents the break-even points. The company was not in profit or loss when no pen was sold and when 6 pens were sold, the profit was $0 at these two points.
The maximum value of the graph represents the maximum profit made by the company. The company made a maximum profit of $120 when 3 pens were sold.
The interval where the function is increasing is from negative infinity to x = 3. This shows that the more pen sold, the higher the profit made.
The interval where the function is decreasing is from x = 3 to positive infinity. This shows that the less pen sold, the lower the profit made.
The approximate average rate of change of the graph from x = 3 to x = 5 is;
\(\begin{gathered} ARC=\frac{f(x_2)-f(x_1)}{x_2-x_1} \\ where: \\ x_1=3 \\ x_2=5 \\ f(x_1)=120 \\ f(x_2)=60 \\ \\ Hence, \\ ARC=\frac{60-120}{5-3} \\ ARC=\frac{-60}{2} \\ ARC=-30 \end{gathered}\)The rate represents a decrease of $30 for every pen sold across the decreasing interval.

Answer:
x = 10
Step-by-step explanation:
Given the 2 equations
12x - 6y = 60
24x + 6y = 300
Adding the 2 equations term by term will eliminate the y- term, that is
36x + 0 = 360
36x = 360 ( divide both sides by 36 )

given a closed box, where the length is twice the height, the width is 10 meters less than the length, and the surface area is 10 times the width times the height, what are the dimensions?
Answers
So the dimensions of the box are:
Length: 20m
Width: 10m
Height: 10m
We can use the information provided in the problem to set up a system of equations. Let H be the height, L be the length, and W be the width.
From the problem, we know:
L = 2H (the length is twice the height)
W = L - 10 (the width is 10 meters less than the length)
2HW + 2LW + 2LH = 10WH (the surface area is 10 times the width times the height)
We can substitute the first and second equations into the third one to obtain:
2H(2H-10) + 2(2H)(2H-10) + 2(2H)(2H) = 10H(2H-10)
Solving this equation we get H = 10m
With this value we can solve for the other dimensions:
L = 2H = 2 * 10 = 20m
W = L - 10 = 20 - 10 = 10m
So the dimensions of the box are:
Length: 20m
Width: 10m
Height: 10m

Answers
Based on the scholarships and grants that Jamal will receive, his estimated cost per year is $25,050.
If his family contributes $21,000, he will have to contribute $4,050.
If Jamal has $0 in savings, the amount to save each month is $337.50.
If Jamal has $1,000 in savings, the amount to save each month is $254.17.
If Jamal has $2,000 in savings, the amount to save each month is $170.83.
What is Jamal's estimated cost?= Cost per year of private university - Scholarships - Work study program
= (25,100 + 8,000 + 1,300 + 750) - 8,200 - 1,900
= 35,150 - 8,200 - 1,900
= $25,050
What amount will he contribute if his family contributes?= Estimated cost - family contribution
= 25,050 - 21,000
= $4,050
What amount should Jamal save?The amount that Jamal should save monthly can be found as:
= (Amount to contribute - Amount already saved ) / Number of months in year
If Jamal has $0, he should save:
= (4,050 - 0) / 12
= $337.50
If Jamal has $1,000:
= (4,050 - 1,000) / 12
= $254.17
If Jamal has $2,000:
= (4,050 - 2,000) / 12
= $170.83

A random number generator is used to create a list of 300 single-digit numbers. Of those 300 numbers, 146 are odd and 154 are even. The number 8 was generated 22 times. What is the experimental probability of an even number other than 8 being generated? Write your answer as a decimal to the nearest hundredths place. 0. 23 0. 35 0. 44 0. 52.
Answers
The experimental probability of an even number, excluding 8, being generated is approximately 0.35.
Out of the 300 single-digit numbers generated, 146 are odd and 154 are even. Additionally, the number 8 was generated 22 times. To find the experimental probability of an even number other than 8 being generated, we need to subtract the occurrences of 8 from the total number of even numbers and then divide it by the total number of numbers.
The total number of even numbers excluding 8 is 154 - 22 = 132. Dividing this by the total number of numbers generated (300), we get 132/300 ≈ 0.44.
Therefore, the experimental probability of an even number, excluding 8, being generated is approximately 0.44, which is closest to option c) 0.35 when rounded to the nearest hundredths place.

d = √((x2 - x1)² + (y2 - y1)²)
where (x1, y1) and (x2, y2) are the coordinates of the two points. Substituting the coordinates of M(6, 16) and Z(-1, 14), we get:
d = √((-1 - 6)² + (14 - 16)²) = √(49 + 4) = √53 ≈ 7.1

The equation of Straight line, perpendicular to line [k]would be y = - x + 5
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of straight line also represents the directly proportional relation as -
y = mx + c
y = mx {c = 0}
m = y/x
or
m = Δy/Δx
where [m] is constant of proportionality.
We have a line [k] that has an equation of y = x - 7
We have the given equation of line -
y = x - 7
Slope of line will be 1.
Slope of the line perpendicular to line [k] will be -
m[p] = -1
Then, the general equation would become -
y = - x + c
For point (7, - 2), we can write -
- 2 = - 7 + c
c = - 2 + 7
c = 5

The rate of consumption of oil in the United States during the 1980s (in billions of barrels per year) is modeled by the function C(t) = 27.08e', where t is the number of years after January 1, 1980. Find the total consumption of oil in the United States from January 1, 1980 to January 1, 1990.
Answers
the total consumption of oil in the United States from January 1, 1980, to January 1, 1990 is approximately 596,533.7 billion barrels.
To find the total consumption of oil in the United States from January 1, 1980 to January 1, 1990, we need to integrate the given function\(C(t) = 27.08e^t\)with respect to time t, over the interval [0, 10], where t is measured in years.
The integral of the function is:
∫\((27.08e^t) dt\)
To solve this integral, we use the fact that the integral of\(e^t\) is \(e^t\)itself. Thus, we get:
27.08∫\(e^t dt = 27.08e^t\)
Now, we need to evaluate the definite integral over the interval [0, 10]:
\(27.08e^t\)| from 0 to 10 =\(27.08(e^{10} - e^0)\)
As e^0 = 1, the expression simplifies to:
\(27.08(e^{10} - 1)\)
Now, we can calculate the value of the expression:
\(27.08(e^{10} - 1) =27.08(22026.47 - 1) = 27.08 * 22025.47 =596533.7\)
Thus, the total consumption of oil in the United States from January 1, 1980, to January 1, 1990 is approximately 596,533.7 billion barrels.
