It takes 7.5 cups of milk to make 1 stick of butter.
Step-by-step explanation:
Given,
Cups of milk used = 30 cups
Sticks of butter made = 4
Unit rate describes how many units of one quantity corresponds to 1 unit of other quantity.
We will find unit rate per butter stick.
Unit rate per butter stick = [tex]\frac{cups\ of\ milk\ used}{No.\ of\ butter\ sticks}[/tex]
Unit rate per butter stick = [tex]\frac{30}{4} = 7.5\ cups\ of\ milk\ per\ butter\ stick[/tex]
It takes 7.5 cups of milk to make 1 stick of butter.
