According to the directions on a can of frozen orange juice concentrate, 1 can of concentrate is to be mixed with 3 cans of water to make orange juice. How many 12 ounce cans of the concentrate are required to prepare 200 6 ounce servings of orange juice?
1 can of concentrate + 3 cans of water = 4 cans total
You need 200 6oz servings or 100 12oz servings (100 12oz cans). set up your ratio 1/4 = x/100
1/4 = concentrate/total
x/100 = concentrate/total
cross multiply and you get 4x = 100 and x = 25
