Question

D7: The monthly cost of producing x electronic components is C(x)=2.15x+2350. a. Find the monthly average cost function. b. Find the average cost for the production of 100 components. c. What is the domain of the average cost function?

Answer 1

a) Average cost is total cost divided by the output.

C(x) = C(x)/x = (2.15x+2350)/x = 2.15 + 2350/x = 2350x^-1 + 2.15

b) C(100)= 2350(100)^-1 + 2.15
