Question

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?
○ gym b charges $1.05 less per hour than gym a.
○ gym b charges $1.50 less per hour than gym a.
○ gym b charges $5.25 less per hour than gym a.
○ gym b and gym a charge the same hourly rate for childcare.

Explanation:

Step1: Convert Gym B rate to hourly

First, find how many 5-minute intervals are in 1 hour: there are $\frac{60}{5}=12$ intervals.
Calculate Gym B's hourly rate: $0.75 \times 12 = 9.00$

Step2: Compare hourly rates

Gym A's rate is $\$9.00$ per hour, Gym B's rate is also $\$9.00$ per hour.

Answer:

Gym B and Gym A charge the same hourly rate for childcare.
