Assume that a firm used $60 million in labor and materials to generate $100 million in total revenues. Other costs included $200,000 in foregone interest, economic depreciation of $40,000, and normal profit of $130,000. The economic profit to this firm is closest to:

A)	$39,712,000.

B)	$40,000,000.

C)	$39,630,000.

Economic profit = total revenue – opportunity costs = total revenue – (explicit + implicit costs). In this case, the labor and material cost of $60 million is the explicit cost. Implicit costs include the $200,000 in foregone interest, economic depreciation of $40,000, and normal profit of $130,000. So, total implicit costs equal $370,000 = $200,000 + $40,000 + $130,000. Thus, economic profit is $100,000,000 - $60,000,000 - $370,000 = $39,630,000.
