To find out after how many months the total cost of each health club will be the same, we can set up equations for the total cost of each club.
Let
For Club A:
- Initial fee = $10
- Monthly fee = $15
- Total cost for
months =
For Club B:
- Initial fee = $25
- Monthly fee = $12
- Total cost for
months =
To find out when the costs are the same, we set the two equations equal to each other:
Now, let's solve for
- Subtract
from both sides:
This simplifies to:
- Next, subtract 10 from both sides:
- Finally, divide both sides by 3:
Thus, after 5 months, the total cost of each health club will be the same.
