Question

A recipe says to use 3cups of flour to make 48 cookies. What is a constant of proportionality that related the number of cookies made ,y, to the number of cups of flower used ,x?

Answer 1

y=16 x=1

Explanation:

For this one, we need to find the unit rate, which means how many cookies we can make using 1 cup of flour. To do that, we need to divide both the flour and the cookies by 3 to get 3/3=1 and 48/3=16. So the total amount of cookies made with one cup of flour is 16. So the constant proportionality is 16,1.
