A fruit punch recipe that serves 20 people calls for 32 fluid ounces of pineapple juice and 48 fluid ounces of orange juice. Mon
Hoochie [10]

Step-by-step explanation:

so the ratio of the recipe is 32/48 of pineapple juice and orange juice.

that can be simplified to the ratio of 2/3.

now, she has only 20 floz of pineapple juice.

20/x = 2/3

60/x = 2

60 = 2x

x = 60/2 = 30

she needs 30 floz of orange juice with the 20 floz of pineapple juice to maintain the prescribed ratio for fruit punch.
