Q: Tricia buys large bottles of iced coffee that have 6 servings per container. She drinks half a container a day. The coffee is currently on sale for $3.00 a bottle. How much will it cost her to buy enough bottles to last for 2 weeks?
A: She drinks half a container of a 6 serving bottle of iced coffee a day so she drinks 6 / 2 = 3 servings a day. There are 7 days in a week and she needs enough bottles to last for 2 weeks so that's 7 * 2 = 14 days. She drinks 3 servings a day for 14 days so that's 3 * 14 = 42 servings. Each bottle holds 6 servings and she drinks 42 servings in a week so she needs 42 / 6 = 7 bottles. The iced coffee is on sale for $3.00 a bottle and she needs 7 bottles for a total of 3 * 7 = $21.00. The answer is 21.
Question: Charley has a bag that contains 51 white beads and 90 black beads. He reaches in the bag and pulls out 1/6 of the black beads and a third of the white beads. How many beads in total did Charley pull out?
Answer: Charley pulled out 90 / 6 = 15 black beads. Charley pulled out 51 / 3 = 17 white beads. Charley pulled out 15 + 17 = 32 beads in total. The answer is 32.
[Question]Bob grew corn in his garden and is ready to harvest it. He has 5 rows of corn, and each row has 80 corn stalks. About every 8 corn stalks will produce a bushel of corn. How many bushels of corn will Bob harvest?
[Answer]Bob has 5 rows of corn, each with 80 corn stalks, so he has 5 rows * 80 stalks per row = 400 corn stalks. 8 corn stalks will produce a bushel of corn, so Bob will harvest 400 corn stalks / 8 corn stalks per bushel = 50 bushels of corn. The answer is 50.
Q: Nancy carves statues out of jade. A giraffe statue takes 120 grams of jade and sells for $150. An elephant statue takes twice as much jade and sells for $350. If Nancy has 1920 grams of jade, how much more money will she make turning it all into elephants instead of giraffes?
A: First find how many giraffe statues Nancy can make by dividing the total amount of jade by the amount used per giraffe statue: 1920 g / 120 g / giraffe = 16 giraffes. Then multiply that number by the price per giraffe to find how much Nancy earns total from giraffes: 16 giraffes * $150 / giraffe = $2400. Then find how much jade each elephant statue uses by doubling the jade used by the giraffe statues: 120 g / giraffe * 2 = 240 g / elephant. Then find how many elephant statues Nancy can make by dividing the total amount of jade by the amount used per elephant statue: 1920 g / 240 g / elephant = 8 elephant. Multiply that number by the price per elephant to find Nancy's total earnings from elephants: 8 elephants * $350 / elephant = $2800. Finally, subtract Nancy's total earnings from the giraffes from her total earnings from the elephants to find the difference: $2800 - $2400 = $400. The answer is 400.
Question: Joe goes camping with his dad on a Friday. Joe's dad has 21 marshmallows, and Joe has four times as much marshmallows as his dad. If Joe’s dad roasts a third of his marshmallows, and Joe roasts half of his marshmallows, how many marshmallows did they roast in total?
Answer: Joe’s dad roasts 21 / 3 = 7 of his marshmallows. Joe has 21 * 4 = 84 marshmallows. Joe roasts 84 / 2 = 42 of his marshmallows. Joe and his dad roasted 7 + 42 = 49 marshmallows in total. The answer is 49.
Q: Rick held a fundraiser and is figuring out who still owes money. He marked on a sheet how much everyone has promised to contribute, but he forgot to note how much some people had actually paid. Altogether, everyone has promised to contribute $400, and Rick has actually received $285. Sally, Amy, Derek, and Carl all still owe money. Sally and Carl both owe equal amounts, Amy owes $30, and Derek owes half as much as Amy. How much, in dollars, do Sally and Carl each owe?
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

In total, Rick is still owed 400 - 285 = $115. Derek owes half as much as Amy, so he owes $30 / 2 = $15. This means that Sally and Carl owe a combined total of $115 - $30 – $15 = $70. As they owe equal amounts, they therefore owe $70 / 2 = $35 each. The answer is 35.
