Two competing gyms each offer childcare while parents work out. Gym A charges $9.00 per hour of childcare. Gym B charges $0.75 per 5 minutes of childcare. Which comparison of the childcare costs is accurate?

Question

SmokeyBrown · Answer

Gym B charges $0.75 for every 5 minutes, and there are 60 minutes in an hour. So, every hour, 5 minutes pass 12 times. That means, effectively that Gym B charges $0.75 * 12 or $9.00 per hour
So, uh, how does that compare to the rate for Gym A?
