Explanation / Answer

ANSWER:

mr = change in total revenue / change in quantity

mc = change in total cost / change in quantity

atc = total cost / no of units

A) Profit maximizes when mr = mc and the output at that point is 4.

B) Price = 1,500

atc = tc / q = 3,500 / 4 = 875

profit = price - atc = 1,500 - 875 = 625

C) Economic profit (4 units) = tr - tc = 6000 - 3500 = 2,500
