Explanation:

Opportunity cost is the value of the forfeited benefits as a result of making a decision in a certain way. Decision making involves choosing one item over others. The cost or value of the option not chosen is the opportunity cost. The value of the forfeited option is the opportunity cost.

In choosing to go to the gym, the forgone activity is studying for the economic exam. The benefits associated with studying for the economic test is the opportunity cost. The value attached to the economic test, such as good grades, passing the test,  or any reward arising from studying for the test, is the forfeited benefit and hence the opportunity cost.
