Answer:
a)
b) On the 5th month, the gym will have the same total cost of $165
Step-by-step explanation:
We can write the following expression for Gym A:

And we can write the following expression for Gym B:

This can we rewritten as

In order to find the total costs at which the gyms are the same, we must set them equal to each other, solve for m, and then substitute m into the equation.

Now we can substitute m into each equation
![20m+65=28m[tex]20(5)+65=28(5)+25\\\\100+65=140+25\\165=165](https://tex.z-dn.net/?f=20m%2B65%3D28m%5Btex%5D20%285%29%2B65%3D28%285%29%2B25%5C%5C%5C%5C100%2B65%3D140%2B25%5C%5C165%3D165)
On the 5th month, the gym will have the same total cost of $165
