[Question]Robert and Teddy are planning to buy snacks for their friends. Robert orders five boxes of pizza at $10 each box and ten cans of soft drinks at $2 each. Teddy buys six hamburgers at $3 each and an additional ten cans of soft drinks. How much do they spend in all?
[Answer]Five boxes of pizza cost 5 x $10 = $50. Ten cans of soft drinks cost 10 x $2 = $20. So, Robert spends $50 + $20 = $70. Six hamburgers cost 6 x $3 = $18. Thus, Teddy spends $18 + $20 = $38. Therefore, they spend $70 + $38 = $108 in all. The answer is 106.
Q: Simeon drinks 64 fluid ounces of filtered water every day. He used to drink this water in 8-ounce-servings. But now, he drinks his water in 16-ounce servings. How many fewer servings per day does it now take Simeon to drink his water than it used to?
A: In 64 fluid ounces, there are 64 / 8 = 8 eight - ounce servings. Using 16 - ounce servings, Simeon now drinks 64 ounces in 64 / 16 = 4 servings. Thus, Simeon now drinks his water in 8 - 4 = 4 fewer servings per day. The answer is 4.
Question: Nick has 60 cans. Each can takes up 30 square inches of space before being compacted and 20% of that amount after being compacted. How much space do all the cans take up after being compacted?
Answer: First find the total amount of space the cans take up before being compacted: 60 cans * 30 sq in / can = 1800 sq in. Then multiply that amount by the percentage of space they take up after being compacted: 1800 sq in * 20% = 360 sq in. The answer is 360.
[Question]Bill is trying to decide whether to make blueberry muffins or raspberry muffins. Blueberries cost $5.00 per 6 ounce carton and raspberries cost $3.00 per 8 ounce carton. If Bill is going to make 4 batches of muffins, and each batch takes 12 ounces of fruit, how much money would he save by using raspberries instead of blueberries?
[Answer]First find how many ounces of fruit Bill will need total: 12 ounces / batch * 4 batches = 48 ounces. Then find how many cartons of blueberries Bill would need: 48 ounces / 6 ounces / carton = 8 cartons. Then multiply that number by the cost per carton to find the total cost of the blueberries: 8 cartons * $5 / carton = $40. Then find how many cartons of raspberries Bill would need: 48 ounces / 8 ounces / carton = 6 cartons. Then multiply that number by the cost per carton to find the total cost of the raspberries: 6 cartons * $3 / carton = $18. Then subtract the cost of the raspberries from the cost of the blueberries to find the difference: $40 - $18 = $22. The answer is 22.
Q: Vinny weighed 300 pounds then lost 20 pounds in the first month of his diet. He continued his diet but each month, he lost half as much weight as he had lost in the previous month. At the start of the fifth month of his diet, he worked harder to lose extra weight then decided to end his diet. If Vinny weighed 250.5 pounds at the end of his diet, how many pounds did he lose throughout the fifth month?
A: In the second month, Vinny lost half as much as he had the first month, so he lost 20 pounds / 2 = 10 pounds. In the third month, he again lost half as much which was 10 pounds / 2 = 5 pounds. And in the fourth month, he lost 5 pounds / 2 = 2.5 pounds. So in total, Vinny lost 20 + 10 + 5 + 2.5 = 37.5 pounds in the first four months. Over his entire diet, he had lost 300 250.5 = 49.5 pounds. So in the fifth month, Vinny must have lost 49.5 pounds total loss 37.5 pounds loss in the first four months = 12 pounds. The answer is 12.
Question: It's Yvette's turn to treat herself and her three best friends to a round of ice cream sundaes. Alicia orders the peanut butter sundae for $7.50. Brant orders the Royal banana split sundae for $10.00. Josh orders the death by chocolate sundae for $8.50 and Yvette orders the cherry jubilee sundae for $9.00. She leaves her waiter a 20% tip. How much will her final bill be?
Answer:
Yvette spent 7.50 + 10 + 8.5 + 9 = $35.00 on ice cream sundaes. Her bill comes to $35.00 and she leaves a 20% tip for the waiter so that's 35 * .20 = $7.00. The bill was $35.00 and she added a $7.00 tip for a total of 35 + 7 = $42.00. The answer is 42.
