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?
A.)Gym B charges $1.05 less per hour than Gym A.
B.)Gym B charges $1.50 less per hour than Gym A.
C.)Gym B charges $5.25 less per hour than Gym A.
D.)Gym B and Gym A charge the same hourly rate for childcare.

Answer 1

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

You need to find out how much Gym B charges for a full hour. There are 60 minutes in an hour. Divide this by 5 to determine how many 5 minute increments are in an hour: 12. A parent paying for 1 hour of child care will need to make 12 payments of .75. 12 times .75 equals $9.00. This means that both gyms charge the same amount per hour.

Answer 2

The answer is d this is because five goes evenly into 60 12 times so 0.75 times 12 is 9.00 hope you enjoy
