Question

You work as an assistant coach on the university basketball team and earn $15 per hour. One day, you decide to skip the hour-long practice and, instead, go to the county fair, which has an admission fee of $9.

Answer 1

Admission to the fair for one day - $9

Hour-long practice pay (opportunity cost) - $15

15 + 9 = 24

You lost $24 on not working at the university for that day. 

Answer 2

The total cost of skipping practice to go to the fair is $9 the opportunity cost is $15 therefore you are loosing $24 because you miss your chance of earning the $15 and you lost $9 from the mony you already had so when you add the together you get $24 hope this helps
