Answer:
Minimum unit cost = 5,858
Step-by-step explanation:
Given the function : C(x)=x^2−520x+73458
To find the minimum unit cost :
Take the derivative of C(x) with respect to x
dC/dx = 2x - 520
Set = 0
2x - 520
2x = 520
x = 260
To minimize unit cost, 260 engines must be produced
Hence, minimum unit cost will be :
C(x)=x^2−520x+73458
Put x = 260
C(260) = 260^2−520(260) + 73458
= 5,858

Answer:
The question has a mistake
Step-by-step explanation:
11d+7c= 172.5
10d+7c= 155.8
By subtraction;
1d+ 0c = 16.7
1d = 16.7
11×16.7+7c=172.5
7c = 172.5-11*16.7
You will get a negative answer yet the cost cannot be negative.
