Answer:
It would take 1 month for the first gym (costs $24 per month) and 4 month for the second gym (costs $39 per month)
Step-by-step explanation:
If you add up $24 and $135 it equals 159. So for the first month you have to pay (in total) $159 dollars. So, if you want to get the same amount of money you have to multiply 39. To find out what number you need to multiply 39 with 4. Then you would have to add $3.
