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

The answer is D. Gym B and Gym A charge the same hourly rate for childcare.

Answer 2

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

Explanation:

The rate of $0.75 per 5 minutes is ...

$0.75/(5/60 h) = $0.75×12/h = $9.00/h

Gym B's hourly rate is $9.00, the same as that of Gym A.
