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

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.

Answer 1

To compare the costs of childcare between Gym A and Gym B, let's first determine the hourly rate for Gym B.

Gym B charges $0.75 for 5 minutes. To find out how much it costs per hour, we need to calculate how many 5-minute intervals are in an hour:

1 hour = 60 minutes Number of 5-minute intervals in 60 minutes = 60 minutes / 5 minutes = 12 intervals

Now, multiply the cost per interval by the number of intervals in an hour:

Cost per hour at Gym B = $0.75 per interval × 12 intervals = $9.00

Now we can compare that with Gym A's charge:

• Gym A charges $9.00 per hour.
• Gym B also charges $9.00 per hour.

Since both gyms charge the same amount for childcare, the correct comparison is:

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