Explanation / Answer

ANSWER:

tr = price * output

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 5.

B) Price = 800

atc = tc / q = 2,400 / 5 = 480

profit = price - atc = 800 - 480 = 320

C) Economic profit (5 units) = tr - tc = 4000 - 2400 = 1,600
