Question

10 Selena Gomez's gym membership costs $180 to sign up and then charges $6 for each visit Demi Lovato's gym membership costs $160 to sign up and then charges $8 for each visit Al how many visits will they have spent the same amount of money? answeri need the equation with the variables on both sides

Answer 1

Answer:

The equation is:

180 + 6x = 160 + 8x

Number of visits = 10

Explanations:

Let the number of visits be x

Sign up fee for Selena Gomez = $180

Charge per visit for selena Gomez = $6

Total amount spent by Selena Gomez = 180 + 6x

Sign up fee for Demi Lovato = $160

Charge pervisit for Demi Lovato = $8

Total amount of money spent by Demi Lovato = 160 + 8x

If the spent the same amount:

Total amount spent by Selena Gomez = Total amount of money spent by Demi Lovato

The equation is:

180 + 6x = 160 + 8x

To know the number of visits they would have made to spend the same amount, we have to solve the above equation and get the value of x

180 - 160 = 8x - 6x

20 = 2x

20 / 2 = x

x = 10

They will make 10 visits
