Question

a new gym membership charges a one - time enrollment fee plus a monthly fee. the total cost, c, in dollars can be represented by the equation c = 35m + 25, where m is the number of months a person is a member. which of the following ordered pairs (m, c) would not be on the graph that represents this relationship? a. (0, 25) b. (1, 60) c. (3, 130) d. (5, 175)

Explanation:

Step1: Substitute m = 0 into the equation

When $m = 0$, $c=35\times0 + 25=25$. So the ordered - pair $(0,25)$ is on the graph.

Step2: Substitute m = 1 into the equation

When $m = 1$, $c=35\times1+25=35 + 25=60$. So the ordered - pair $(1,60)$ is on the graph.

Step3: Substitute m = 3 into the equation

When $m = 3$, $c=35\times3+25=105 + 25=130$. So the ordered - pair $(3,130)$ is on the graph.

Step4: Substitute m = 5 into the equation

When $m = 5$, $c=35\times5+25=175 + 25=200
eq175$. So the ordered - pair $(5,175)$ is not on the graph.

Answer:

D. (5, 175)
