Question

A local gym charges nonmembers $10 per hour to use the tennis courts. Members pay a yearly fee of $300 and $4 per hour for using the tennis courts. Write and solve an equation to find how many hours you must use the tennis courts to justify becoming a member.

Answer 1

Nonmembers: $10 per hour = 10h
Members: $300 and $4 per hour = 300 + 4h

10h > 300 + 4h
6h > 300
h > 50

You'd need to use it for more than 50 hours.
