Minimum average cost
the cost of producing x units of a product is modeled by
c = 100 + 25x - 120 ln x, x ≥ 1.
(a) find the average cost function ć.
(b) find the minimum average cost analytically. use a graphing utility to confirm your result.

a)

b)

Step-by-step explanation:

Given that

C = 100 + 25 x - 120 ln x   ,x ≥ 1.

The average cost function given as

Therefore

To find average minimum cost

100 + 120 (1-lnx) = 0

ln x =1.833

x=6.25
