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.

Answer 1

Answer:

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

Explanation:

Given,

In gym A,

Hourly charges = $ 9.00

While, In gym B,

Charges for 5 minutes = $ 0.75

So, the charges for 1 minute = $\frac{\text{Charges for 5 minutes}}{5}$

$=\frac{0.75}{5}$

$=\ 0.15$

∵ 1 hour = 60 minutes,

Thus, the charges for 1 hour = 60 × charges for 1 minute,

= 60 × 0.15

= $ 9.00

Hence, the charges in gym A = charges in gym B,

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