The table shows the price for different numbers of cupcakes: Number of Cupcakes Price (in dollars) 3 12 4 16 5 20 7 28 Does this table of numbers represent a proportional relationship?

Look at it this way:

3 x 4 = 12 

4 x 4 = 16

5 x 4 = 20

7 x 4 = 28

Your proof is true because it is x4 the next value.

12 + 4 = 16

16 + 4 = 20

20 + 4 = 24

Hope I helped! :)
