Answer 1

Answer:

a)$20m+65=28m+25$

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:

$20m+65$

And we can write the following expression for Gym B:

$0.8(35m)+25$

This can we rewritten as

$28m+25$

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.

$20m+65=28m+25\\\\8m=40\\\\m=5$

Now we can substitute m into each equation

$20m+65=28m[tex]20(5)+65=28(5)+25\\\\100+65=140+25\\165=165$

On the 5th month, the gym will have the same total cost of $165
