Answer:

10 visits

Explanation:

Let's model the expressions:

  • LA Fitness = 50 + 2x
  • 24 Hour Fitness = 30 + 4x

Now set them to equal each other to find x, the number of visits

50 + 2x = 30 + 4x Subtract 2x

50 = 30 + 2x Subtract 30

20 = 2x Divide by 2

10 = x

After 10 visits to the gym, the cost will be the same.
