Gym A charges a registration fee of $74 plus $33 per month for members. Gym B charges a registration fee of $164 plus $18 per month for members. After how many months would the total cost at Gym A and Gym B be the same for members?

Answers

Answer:

The total charge at Gym A and Gym B would be the same at 6 months

Step-by-step explanation:

The model for the charges of both Gyms is made of the registration fee plus a variable quantity per month.

Let's call m the number of months for members.

Gym A charges $74 plus $33 per month, thus:

$C_a=74+33m$

Gym B charges $164 plus $18 per month, thus:

$C_b=164+18m$

We want to find out the number of months needed for both charges to be the same, thus:

$74+33m=164+18m$

Subtracting 74 and 18m:

$33m-18m=164-74$

Simplifying:

$15m=90$

Dividing by 15:

$m=90/15=6$

m=6

The total charge at Gym A and Gym B would be the same at 6 months
