Given that 8 cups equals 100% of this punch, we need to figure out how many coups does 15% of sorbet make. This is how we do this: 8 (cups) : 100% (the entire amount of punch) = x (the number of sorbet cups) : 15% (the amount of sorbet used) So: x : 15 = 8 : 100 100x = 15 * 8 100x = 120 x = 1.2 The answer is 1.2 cups of sorbet were used in this punch.
