Question

A punch recipe says to mix 4 cups pineapple juice, 8 cups orange juice, and 12 cups seltzer in order to make 18 servings of punch. How many cups of each ingredient do you need to make 108 cups of punch? How many servings can be made from 108 cups of punch? For every cup of seltzer you use, how much orange juice do you use?

Answer 1

108/18 = 6

We know how many servings there are in 108 cups.

4 × 6 = 24
8 × 6 = 48
12 × 6 = 72

You need 24 cups of pineapple juice, 48 cups of orange juice, and 72 cups of seltzer to make 108 cups of punch.

I hope that helped! :)
