Question

A gym charges $8.75 for each swimming class and a one-time registration fee of $12.50. A student paid a total of $56.25. How many swim classes did the student take? *

Answer 1

Take the total cost and subtract the registration fee.
56.25-12.5=$43.75
The remainder is what was spent on swim classes so divide by the cost of the swim classes.
$43.75/8.75=5 swim classes
