Question

The equation 15m + 35 = 10(m + 5) can be used to find when the cost of two different gyms will be the same. After how many months m will the cost of the gyms be the same?

Answer 1

3 months

Explanation:

To find the amount of months, m, we will have to solve the equation given. If you don't have any experience solving equations, this could be tricky, but hopefully my work below will be helpful.

15m + 35 = 10(m + 5)

15m + 35 = 10m + 50

15m - 10m + 35 = 10m - 10m + 50

5m + 35 = 50

5m + 35 - 35 = 50 - 35

5m = 15

5m/5 = 15/5

m = 3

After 3 months the cost of the gyms will be the same. Let me know if you need more clarification or were confused by my work. :)
