A fitness club charges

Question

A fitness club charges its members a one-time fee of $40 and a monthly rate of $25. Let m represent the number of months. Write an expression for the total amount paid after m months. Then find how much a customer will have paid after 5 months. Expression: No spaces! Cost: dollars

Answer 1

This question asks you to write an expression which exactly follows the y = mx + b slope intercept formula.

In this question, the slope (m) is the monthly rate ($25), and the y-intercept (b) is $40. After plugging in our values of m and b, we get the following expression:

cost($) = 25m + 40

To find out how much a customer has paid after 5 months, simply plug in 5 for m, then solve algebraically (and remember to include the unit of dollars).
