galina1969 [7]

The opportunity cost of producing 3 military outfits is -30.

<h3>What is the opportunity cost of producing military outfits?</h3>

Opportunity cost = change in consumer products / change in military

The opportunity cost of producing 3 military outfits = (85 - 115) / (3 - 2) = -30

The opportunity cost of producing 4 military outfits = (50 - 85) / (4 - 3) = -35

The opportunity cost of producing 5 military outfits = (0 - 50) / (5 - 4) = -50
