Textbook Question
Suppose the cost of producing x lawn mowers is C(x) = −0.02x²+400x+5000.
a. Determine the average and marginal costs for x = 3000 lawn mowers.

1
To find the average cost for producing x lawn mowers, use the formula for average cost, which is A(x) = C(x) / x, where C(x) is the total cost function.
Substitute x = 3000 into the cost function C(x) = -0.02(3000)² + 400(3000) + 5000 to calculate C(3000).
Calculate the average cost A(3000) by dividing the total cost C(3000) by 3000.
To find the marginal cost, first compute the derivative of the cost function C(x) to get C'(x), which represents the marginal cost.
Evaluate the marginal cost at x = 3000 by substituting 3000 into the derivative C'(x).
