If the average cost per unit C(x) to produce x units of plywood is given by:
C(x) = 900%2F%28%28x%2B30%29%29
:
What do 600 units cost? Round your answer to the nearest cent.
;
You are looking for the total cost which is
no. of units sold (x) times cost/unit, which is the given equation
:
C(x) = x*900%2F%28%28x%2B30%29%29
:
Substitute 600 for x in the given equation:
C(x) = 600*900%2F%28%28600%2B30%29%29
:
C(x) = 600*900%2F630
:
C(x) = 600 * 1.42857
:
C(x) = $857.14
