The marketing department of a local shoe company found that approximately 550 pairs of running shoes are sold monthly when the price of each pair is $100. It was also observed that, for each $1 reduction in price, an additional 20 pairs of
running shoes are sold monthly. What price should the shoe store charge for a pair of running shoes in order to maximize revenue?
Answer:
The price that maximizes the revenue is $63.75
Step-by-step explanation:
Analyzing the statement one after the other.
[tex]Initial\ Quantity = 550[/tex] ---- When ----- [tex]Initial\ Price = \$100[/tex]
When there's a reduction of $1, we have:
[tex]Quantity = 550 + 20x[/tex] and [tex]Price = 100 - x[/tex]
Where x represents the maximum reduction
At this point, we need to calculate the revenue (R)
[tex]R = Quantity * Price.[/tex]
[tex]R = (550 + 20x) * (100 - x)[/tex]
Open Brackets
[tex]R = 55000 - 550x + 2000x - 20x^2[/tex]
[tex]R = 55000 +1450x - 20x^2[/tex]
Differentiate both sides with respect to x
[tex]\frac{dR}{dx} = 0 + 1450 - 40x[/tex]
[tex]\frac{dR}{dx} = 1450 - 40x[/tex]
To maximize revenue;
[tex]\frac{dR}{dx} = 0[/tex]
So:
[tex]1450 - 40x = 0[/tex]
[tex]1450 =40x[/tex]
Solve for x
[tex]x = 1450/40[/tex]
[tex]x = 36.25[/tex]
Recall that:
[tex]Price = 100 - x[/tex]
Substitute [tex]x = 36.25[/tex]
[tex]Price = 100 - 36.25[/tex]
[tex]Price = 63.75[/tex]
Hence:
The price that maximizes the revenue is $63.75

25. What is the slope of the line that passes through the points (8, 1) and (5, 7)?
9514 1404 393
Answer:
-2
Step-by-step explanation:
You can use the formula for slope (m) to find it:
m = (y2 -y1)/(x2 -x1)
m = (7 -1)/(5 -8) = 6/-3 = -2
The slope of the line is -2.

Joe's employer will reimburse him $0.07 per mile driven. If Joe drives 179.53 miles on a business trip, what is his mileage reimbursement? Round your answer to the nearest cent.
Answer:
$12.27
Step-by-step explanation:
.07 times 179.53 is 12.5671 so rounded to 12.27
The mileage reimbursement for Joe is: $12.27 to the nearest cent.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
WE have been given that Joe's employer will reimburse him $0.07 per mile driven.
If the employer reimburses $0.07 per mile driven, we just need to multiply $0.07 by the number of miles that Joe drives.
So, the mileage reimbursement for Joe is:
0.07 x 179.53 = 12.5671
so rounded to 12.27
Therefore, The mileage reimbursement for Joe is: $12.27 to the nearest cent.

It is common in many industrial areas to use a filling machine to fill boxes full of product. This occurs in the food industry as well as other areas in which the product is used in the home, for example, detergent. These machines are not perfect, and indeed they may A, fill to specification, B, underfill, and C, overfill. Generally, the practice of underfilling is that which one hopes to avoid. Let P(B) = 0.002 while P(A) = 0.980.
the length of a rectangle is 5 less than twice its width. the perimeter is 26 meters. find the dimensions of the rectangle.
Step-by-step explanation:
Let x be the length of rectangle and y its width.
P is the perimeter.
So it is given that length is 5 less than twice its width
x=2y-5 so 2y=x+5
also P=2x+2y=26
lets find x
we know 2y=x+5 we replace 2y on P=2x+2y=26
so 26=2x+(x+5)
26=3x+5
21=3x
x=7
so we have that 2y=x+5 so 2y=7+5=12
y=6
we found
length=7
and
width=6
