Q: Blake wants to spend his Friday making milkshakes for his family. He knows that he needs 4 ounces of milk and 12 ounces of ice cream for each milkshake. If he has 72 ounces of milk and 192 ounces of ice cream, how much milk will be left over when he is done?
A: He has enough milk to make 18 milkshakes because 72 / 4 = 18. He has enough ice cream to make 16 milkshakes because 192 / 12 = 16. He can only make 16 milkshakes because 16 < 18. He will use 64 ounces of milk because 16 x 4 = 64. He will have 8 ounces of milk left because 72 - 64 = 8. The answer is 8.

Q: Ashley wants a champagne toast at her wedding. She wants to serve 2 glasses of champagne to each of her 120 wedding guests. 1 bottle of champagne has 6 servings. How many bottles of champagne will she need?
A: She wants to serve 2 glasses of champagne to each of her 120 wedding guests so that's 2 * 120 = 240 servings. Each bottle holds 6 servings and she needs 240 servings so that's 240 / 6 = 40 bottles of champagne. The answer is 40.

Q: Shara borrowed money from her brother 6 months ago. She returned $10 per month to her brother. Currently, she was able to return half of the money she borrowed. How much will she still owe her brother 4 months from now?
A:
For 6 months, Shara was able to return $10 x 6 = $60 to her brother. Since she already returned half of the money, then this means she currently owes her brother $60. Four months from now, she will be able to pay an additional $10 x 4 = $40. Thus, she will still owe her brother $60 - $40 = $20 four months from now. The answer is 20.
