4 * 1/3 = 1,3
4 * 4/5 = 3,2
4 + 1,3 + 3,2 = $8,5 million
C is the answer to this problem
Answer:
cant see the graph to answer.
Step-by-step explanation:
A.) Revenue = price * quantity = px = -1/20x^2 + 1060x
R(x) = -1/20x^2 + 1060x.
b.) Profit = Revenue - Cost = R(x) - C(x) = -1/20x^2 + 1060x - 120x - 5000
P(x) = -1/20x^2 + 940x - 5000
c.) For maximum profit, dP/dx = 0
-1/10x + 940 = 0
1/10x = 940
x = 940 * 10 = 9,400
x = 9,400
Maximum profit = P(9400) = -1/20(9400)^2 + 940(9400) - 5000 = $4,413,000
d.) The price to be charged for maximum profit = -1/20(9400) + 1060 = $590
7/8 yd -2/3 yd
= 21/24 yd -16/24 yd
= (21 -16)/24 yd
= 5/24 yd . . . . . difference between length and width
_____
This is (5/24)*36 = 7 1/2 inches.
