A gym charges $27.95 per month and a one-time membership fee of $40. Another gym offers a monthly charge of $18.25 and a one-time membership fee of $180. After how many months will the cost be the same?

14 months

Step-by-step explanation:

To find the answer you can say that the price of both gyms is equal:

27.95x+40=18.25x+180, where x is the number of months

Now, you can solve for x:

27.95x-18.25x=180-40

9.7x=140

x=140/9.7

x=14.43

According to this, the answer is that the cost will be the same after 14 months.
