Question

What is the constant of proportionality for the relationship between the number of cups of flour and the number of batches of cookies?
0.25
0.5
2
4

A. 12 in. by 22 in. by 4 in.
B. 10 in. by 20 in. by 5 in.
C. 14 in. by 24 in. by 2 in.
D. 10 in. by 24 in. by 6 in. "

Answer 1

So in order to find the answer, let us analyze the given graph first. As we can see, for every 2 cups of flour you get 1 batch of cookies. So this gives us the ratio is 2 to 1. When we say constant proportionality, this is the constant value of the ratio of two proportional quantities. Since for every 2 cups added, the batch of cookies is increased by 1, which gives us the constant proportionality of 2. Hope this answer helps.
