Astudent has only a few hours to prepare for two different exams this afternoon. the above table shows alternative possible exam scores with three alternative uses of the student's time. the opportunity cost of scoring a 94 on the economics exam rather than a 77 is: ) 8 points on the history exam. b) 14 points on the history exam. c) 15 points on the history exam. d) 17 points on the history exam.

c) 15 points on the history exam

Explanation:

The computation of the opportunity cost is shown below:

= Third possibility in history - first possibility in history

= 91 - 76

= 15 points

Simply we deduct the first possibility in history from the Third possibility in history in order to find out the opportunity cost.

Hence, the most appropriate option is c.
