Answer 1

a. The relationship is NOT proportional

b. The constant of proportionality is 0.4

Explanation:

a. The numbers in the table are not proportional. We can tell that by dividing the top numbers by the bottom numbers they're matched with to find and compare ratios. 2/72=0.0277, but 8/296=0.0270, so since they're not equal, they're not proportional.

b. We find the constant of proportionality by doing the same thing as we did to find the ratios above. So 3/7.50= 0.4. To make sure the rate is the same, we'll also check that 7/17.50=0.4. Since it does, we know that that's the answer.

Answer 2

1. It is not proportional because if it is going up 36 every time, number 5 should be 180.

2. The difference between 3 and 7 cans of red bull are $10. 4 cans are $10. Each can is 2.50.
