Answer 1

To find the constant of proportionality, we can take any two pairs of values and divide the number of M&Ms by the number of raisins. Let's take the first and second pairs:

First pair: 3 M&Ms, 6 raisins
Second pair: 5 M&Ms, 10 raisins

For the first pair, 3 M&Ms ÷ 6 raisins = 0.5
For the second pair, 5 M&Ms ÷ 10 raisins = 0.5

Since we get the same value for both pairs, the constant of proportionality is 0.5.

Therefore, the correct answer is A) 1.
