Answer:
Total cost of skipping practice and going to the movies = $24
Step-by-step explanation:
Total cost of going to movie and skipping practice, will be inclusive of opportunity cost of earning from swimming lessons.
Here coach earns $15 per hour
Opportunity cost = $15 per hour for hours forgiven due to movie.
Real cost = $9 for movie entry.
The total cost of skipping practice and going to the movies = $15 + $9 = $24
Since its hour long practice, that has to be skipped, assumed the practice session of an hour is missed, in case it is more than an hour then $15 X number of hours + $9 entry fee of movie.
Since its hour long practice, total cost of skipping practice and going to the movies = $15 + $9 = $24
