Solve the problem.
-Suppose that the dollar cost of producing $x$ radios is $c ( x ) = 200 + 10 x - 0.2 x ^ { 2 }$. Find the average cost per radio of producing the first 30 radios.
A) $10.67
B) $270.00
C) $120.00
D) $320.00

Question

Quizplus · Accepted Answer

The average cost per radio for producing the first 30 radios is found by dividing the total cost of producing 30 radios by 30. The total cost for 30 radios is $c(30) = 200 + 10(30) - 0.2(30)^2 = 200 + 300 - 180 = 320$. Therefore, the average cost per radio is $320 / 30 = 10.67$.
