Question

It costs $35 to join a gym. The monthly fee is $25. Write and graph an equation in two variables that represents the total cost of a gym membership. Let m represent the number of months and c represent the total cost of the gym membership. An equation in two variables that represents the total cost of a gym

Answer 1

The equation would be: C = 25M + 35

Answer 2

The equation would be: C = 25M + 35

This is an equation in slope intercept form (y = mx + b). The slope is 25, because the cost goes up by 25 per month. The y-intercept is 35, because that is where is starts.

To graph it, start on the y-axis at 35. Then, move up $25 each month.
