Question

A company produces x units of output at a total cost of
1/3x3 – 18x2 + 160x. Find (1) Output at which marginal
cost is minimum (2) Output at which average cost equal
to marginal cost.

Answer 1

Answer:

average cost is

(1/3 x^3 – 18x^2 + 160x)/x

= 1/3 x^2 - 18x + 160

marginal cost is

x^2-26x+160

so, where is

1/3 x^2 - 18x = x^2 - 26x ?
