Question

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? Yes, because 4 times the price is the number of cupcakes Yes, because the price is 4 times the number of cupcakes No, because the price of 4 cupcakes should be $13 and not $12 No, because the price of 5 cupcakes should be $60 and not $20

Answer 1

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! :)

Answer 2
