Question

Skyzone charges $20 per month and $4 each time you visit. Zipcity charges $30 per month

and $2 each time you visit. How many visits would it take in one month for both jump places to
be the same total price? What is the total cost for each gym?

Answer 1

Answer: 5 visits

Explanation:

Let x be months and y be visits. We will write expressions for both Skyzone and Zipcity.

Skyzone:

$20x + $4y

Zipcity:

$30x + $2y

Since we want to see when they will be equal, we will set the expressions equal to each other and solve. We are counting the number of visits per month, so we will set x equal to 1.

$30(1) + $2y = $20(1) + $4y

$30 + $2y = $20 + $4y

$10 + $2y = $4y

$10 = $2y

5 = y

5 visits.
