During a sale, a shop gave a storewide discount of 20%. Mrs Tan bought a handbag for $96. What was the price of the handbag before the discount?
Answers
Answer:
120 dollars ($120)
Step-by-step explanation:
(x = original price)
(0.8 is from 0.2 (20 percent) being discounted, meaning 96 is 80% {0.8} of the original price)
x × 0.8 = 96
÷ 0.8 ÷0.8
x = 120
check: 120 × 0.2 = 24
(20 percent of 120 is 24)
120 - 24 = 96
So, the original price was 120 dollars
----
remember: percentage can be found by multiplying by 0.percentage
for example, 10% of 100 = 100 × 0.10 = 10
also written as: 100 × 0.1 = 10

The following data give the distribution of the types of houses in a town containing 22,000 houses:House TypecapegarrisonsplitFrequency550088007700Percentage25%35%40%
Answers
The distribution of the types of houses in the town is as follows:
- 25% of houses are Cape houses
- 35% of houses are Garrison houses
- 40% of houses are Split houses.
According to the given data, there are 22,000 houses in the town and they are classified into three types: Cape, Garrison, and Split. The frequency of Cape houses is 5,500, the frequency of Garrison houses is 8,800, and the frequency of Split houses is 7,700.
To find the percentage of each house type, we need to use the formula:
Percentage = (Frequency / Total number of houses) x 100
For Cape houses, the percentage is (5,500 / 22,000) x 100 = 25%
For Garrison houses, the percentage is (8,800 / 22,000) x 100 = 35%
For Split houses, the percentage is (7,700 / 22,000) x 100 = 40%
Therefore, the distribution of the types of houses in the town is as follows:
- 25% of houses are Cape houses
- 35% of houses are Garrison houses
- 40% of houses are Split houses.

Answer:
h = 0
Step-by-step explanation:
Ok, I got you.
To begin, everyone knows that y = mx + b is the equation for any slope-intercept form problem.
y = the y - value of a point
m = the slope
x = the x - value of a point
b = the y - intercept (or where the line starts)
So, you are given the slope, and you're given the y - value. But, you don't have the x - value in the second point.
That mean's you're going to have to use the first point, because you're given both the x and y values, to find the y - intercept.
Simply, plug in the y and x values where they belong.
2 = 6 (-1) + b
(Remember the 6 is the slope)
Now, solve for b.
2 = -6 + b
8 = b
Now, you know the y - intercept.
So, you can find the value of h in the second point. Since you don't know the x - value, plug in what you do know and solve for y.
So...
8 = 6 (x) + 8
(Remember 6 is the slope and 8 is the y - intercept)
Now, solve for x.
8 = 6x + 8
0 = 6x
0 = x
The value of h is 0.

You are planning to completely delta hedge your ABC
share holdings. How many call options
will you need to hedge holding 480 shares of a company, if you know
that the option's delta is 0.6?
Answers
In order to completely delta hedge 480 shares of ABC company with an option delta of 0.6, you would need 3 call options.
To completely delta hedge your holdings of 480 shares of ABC company, you would need to calculate the number of call options required based on the delta of the option. The delta represents the change in the option price relative to the change in the underlying stock price. In this case, since the delta is given as 0.6, it means that for every $1 increase in the stock price, the option price will increase by $0.6.
To calculate the number of call options needed for delta hedging, you can use the following formula:
Number of call options = (Delta * Number of shares) / 100
Plugging in the given values, we have:
Number of call options = (0.6 * 480) / 100
Number of call options = 2.88
Since you cannot have a fractional number of options, you would need to round up to the nearest whole number. Therefore, you would need 3 call options to hedge your 480 shares of ABC company.
In summary, to completely delta hedge 480 shares of ABC company with an option delta of 0.6, you would need to acquire 3 call options.

(let x1
Answers
Now, we can solve this system of inequalities using the Simplex method or graphically. The solution will provide the minimum cost and the corresponding amounts of ore purchased from each site.
To solve this problem, let's first assign variables to the amount of ore purchased from each site.
Let x1 represent the amount of ore type 1 purchased and x2 represent the amount of ore type 2 purchased.
We can set up the following equations based on the given information:
-
Copper: 0.20x1 + 0.30x2 ≥ 9
- Zinc: 0.20x1 + 0.25x2 ≥ 7
- Magnesium: 0.15x1 + 0.10x2 ≥ 6
Next, we need to minimize the cost function, which is:
Cost = 90x1 + 120x2

#SPJ11
To find the least costly way for Blacktop Refining to buy enough ore to extract at least 9 tons of copper, 7 tons of zinc, and 6 tons of magnesium, we can set up a system of equations.
Let x1 represent the number of tons of ore type 1 to purchase and let x2 represent the number of tons of ore type 2 to purchase.
The total cost can be calculated using the cost per ton for each ore type:
Cost = ($90 * x1) + ($120 * x2)
We also need to set up equations for the amount of each mineral extracted:
Copper = 0.20 * x1 + 0.30 * x2
Zinc = 0.20 * x1 + 0.25 * x2
Magnesium = 0.15 * x1 + 0.10 * x2
To minimize the cost, we need to find the values of x1 and x2 that satisfy the constraints (9 tons of copper, 7 tons of zinc, and 6 tons of magnesium) while minimizing the cost function.
Let's solve this system of equations using linear programming.
First, we need to express the cost function in terms of a single variable. Let's solve for x1 in terms of x2 from the Copper equation:
x1 = (9 - 0.30 * x2) / 0.20
Substituting this expression for x1 into the Zinc equation:
Zinc = 0.20 * ((9 - 0.30 * x2) / 0.20) + 0.25 * x2
Simplifying the equation:
Zinc = 9 - 0.30 * x2 + 0.25 * x2
Combining like terms:
Zinc = 9 - 0.05 * x2
Now we have two equations, Copper = 9 - 0.30 * x2 and Zinc = 9 - 0.05 * x2.
Substituting these equations into the Magnesium equation:
Magnesium = 0.15 * ((9 - 0.30 * x2) / 0.20) + 0.10 * x2
Simplifying the equation:
Magnesium = (27 - 0.90 * x2) / 0.20 + 0.10 * x2
Combining like terms:
Magnesium = 135 - 4.50 * x2 + 0.10 * x2
Now we have three equations: Copper = 9 - 0.30 * x2, Zinc = 9 - 0.05 * x2, and Magnesium = 135 - 4.50 * x2 + 0.10 * x2.

In exponential growth functions, the base of the exponent must be greater than 1. How would the function change if the base of the exponent were 1
Answers
If the base of the exponent in an exponential growth function were 1, the function would become constant, with a fixed value of 1 regardless of the value of x.
In exponential growth functions, the base of the exponent represents the factor by which the function grows at each step. When the base is greater than 1, the function experiences exponential growth, with the values increasing rapidly over time. However, if the base of the exponent were 1, the function would change significantly.
When the base of the exponent is 1, the function becomes constant. This is because any number raised to the power of 1 remains unchanged. Therefore, if the base is 1, the exponential function will have a constant value and will not exhibit any growth or decay.
Mathematically, an exponential function with a base of 1 can be represented as:
f(x) = 1^x
No matter what value of x is used, the result will always be 1. For example, if we substitute different values for x, such as x = 2 or x = -3, we get:
f(2) = 1^2 = 1
f(-3) = 1^(-3) = 1
In both cases, the result is always 1.
