Question

Assume that each situation can be expressed as a linear cost function. Find the cost function for each case. Marginal cost $90.00 ; 150 items cost $16,000.00 to produce.

Answer 1

Marginal cost = 90 on a linear cost function means

Cost = 90 * units + someconstant.

Plug in cost = 16,000 and units = 150 to solve for "someconstant". (The answer is 2500)
