A snack mix recipe calls for 10 cups of cereal and 4 cups of pretzel sticks.
What is the constant of proportionality that relates the number of cups of cereal, y, to the number of cups of pretzel sticks, x?
Question 5 options:
0.4
14
2.5
6
To find the constant of proportionality, we need to determine the ratio of cereal to pretzel sticks.
10 cups of cereal corresponds to 4 cups of pretzel sticks.
Therefore, the constant of proportionality is 10/4 = <<10/4=2.5>>2.5.
So, the correct option is 2.5.
