Solve the problem. Round to two decimal places unless otherwise indicated.
-If the average cost per unit C(x) to produce x units of plywood is given by C(x) $C ( x ) = \frac { 1200 } { x + 40 }$ , what do 400 units cost?
A) $1199.90
B) $120.00
C) $12000.00

Quizplus · Accepted Answer

To find the cost of 400 units, substitute x = 400 into the function: C(400) = 1200 / (400 + 40) = 1200 / 440 = 2.72727. The total cost for 400 units is 400 * 2.72727 = $1090.91.
