Question

Rudy is making punch for his birthday party. First, he pours 20 cups of ginger ale into his punch bowl. Then, he adds two 64-fluid-ounce bottles of grape juice. How many cups of punch does Rudy have in all?

Answer 1

Rudy has a total of 36 cups of punch for his birthday party after adding two 64-fluid-ounce bottles of grape juice to the 20 cups of ginger ale he started with.

Step-by-step explanation:

Rudy is making punch for his birthday party and needs to calculate the total amount of punch in cups. Rudy starts with 20 cups of ginger ale and adds two 64-fluid-ounce bottles of grape juice. To determine how many cups are in each bottle, first, you find the unit equivalence:

• 1 cup = 8 fluid ounces

Next, calculate the amount of grape juice in cups:

• 64 fluid ounces ÷ 8 fluid ounces/cup = 8 cups

Since there are two bottles, multiply the amount in one bottle by two:

• 8 cups/bottle × 2 bottles = 16 cups

Add the grape juice to the ginger ale to find the total:

• 20 cups + 16 cups = 36 cups

Rudy has a total of 36 cups of punch for his birthday party.

Answer 2

Answer: 28 cups

Step-by-step explanation:

8 ounces = 1 cup

64 ounces = 8 cups

20 + 8 = 28

28 cups in all
