The total cost (in dollars) of producing x food processors is
C(x)= 2500+90x-0.2x^2 (x-squared)
(A) Find the exact cost of producing the 61st food processor.
(B) Use the marginal cost to approximate the cost of producing the 61st food processor.
(a) the cost of producing x = 60 processors is
C(x = 60) = 2500 + 90 * 60 - 0.2 * 60^2 = 7180
The cost of producing x = 61 ...
The solution shows how to calculate the marginal cost in detail, using step by step formula.
