Question

PLEASE HELP I DON'T UNDERSTAND THIS!!!

The table shows the relationship between the number of spinning classes a person takes at a gym in one month and the total cost of gym membership for that month.

Number of Spinning Classes Taken in One Month
2

4

6

8
Monthly Cost of Gym Membership

42

56

68

80

​Is this a proportional relationship?

Answer 1

This is a non-proportional relationship

Explanation:

A proportional table has a constant of proportionality in that y divided by x always equals the same value.

In this case:

42/2 = 21

56/4 = 14

68/6 = 11.333

80/8 = 10

The value is not similar
