A gym charges its members a one-time $10.00 sign-up fee, and $25 per month. The function
rule f(x) = 25x + 10 describes the relationship between the number of months x, and the
total cost of membership f(x). If a gym member paid $185.00 how many months did the
gym member pay for?

We can write the equation 25x+10=185 where 25 represents the cost per month, x represents the number of months, 10 represents the sign-up fee and 185 represents the total cost.

To isolate the variable, first subtract 10 from both sides of the equation.

This new equation should look like: 25x=175

The next step in isolating the variable is to divide both sides of the equation by 25.

Doing this, you should be left with the final equation x=7 which is your answer.
