the cost for a personal fitness plan at gym A is $76.50 for 8.5 hours. at gym B the cost is $10.50 for 3/4 hour. which plan offers the best deal?

Question

76.50 dollars for gym a. 10.50 dollars for 3/4 hours at gym b

Answer 1

Fitness Cost (C) = Cost per hour(H) x Time (T)

Fitness Cost by gym A (Ca) = 76.5

76.5 = Ha x 8.5

Ha = 9

Fitness Cost by gym B (Cb) = 10.5

10.5 = Hb x 3/4

Hb = 14

 

Gym A is cheap.

 

Answer 2

To compare the deals, you want to compare the price at each one for an equal amount of time, such as per hour.

 

The cost per hour at gym A is 76.5 / 8.5, which is $9 per hour

 

The cost per hour at gym B is 10.50 / (3/4) = 10.50 / .75, which is $14 per hour

 

So gym B is a better deal.
