Four cups of pure water are added to a 20-cup bowl of punch that is 75% juice. What percentage of the new punch is juice? Original(Cups)Added(Cups)New(Cups)Amount of Juice150 Amount of Punch204

The original punch contains 20 × 0.75 = 15 cups of juice. Adding 4 cups of pure water increases the total to 24 cups but does not change the amount of juice, so the new percentage is 15 ÷ 24 × 100 = 62.5%. The correct choice is C, 62.5%.
