Question

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

Answer 1

For proportionality constant problems, set up the equation as,

$x=Ky$,

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.

$15=K(10)\\K=\frac{15}{10}= \frac{3}{2}$,

$30=K(20)\\K=\frac{30}{20}= \frac{3}{2}$, and

$45=K(30)\\K=\frac{45}{30}= \frac{3}{2}$.

Hence, the proportionality constant, in this case K, is equal to $\frac{3}{2}$ or 1.5. First answer choice is correct.

ANSWER: 1.5

Answer 2

Answer:

1.5

Step-by-step explanation:

The answer is 1.5 because if you were to take 1 whole of the cheddar corn, it'll be 10 and half of that is 5 and when you add those together you get 15 which is 1.5 of 10. I know this is right because i took the quiz and got 100%
