The table shows the ratio of caramel corn to cheddar corn in a bag. what is the constant of proportionality?

cheddar corn caramel corn
10 15
20 30
30 45

answers:
1.5
5
15
0.67

i got 5 is this right because the averages are 5,10, and 15 so it would be 5?

For proportionality constant problems, set up the equation as,

,

Where x and y are the two variables you are comparing and K is the proportionality constant. If we take Caramel Corn  values as x and Cheddar Corn values as y, and then solve for K for each ratio lines, we will get the same answer. Let's check.

,

, and

.

Hence, the proportionality constant, in this case K, is equal to or 1.5. First answer choice is correct.
