Q: James dumps his whole collection of 500 Legos on the floor and starts building a castle out of them. He uses half the pieces before finishing and is told to put the rest away. He puts all of the leftover pieces back in the box they came from, except for 5 missing pieces that he can't find. How many Legos are in the box at the end?
A: James starts with 500 Legos and uses half of them, leaving 500 / 2 = 250 Legos unused. He puts those unused Legos away but since he's missing 5 he only puts 250 - 5 = 245 Legos away. The answer is 245.
Question: David has a store where he sells cell phones. When he takes inventory at the end of the day, he notices that he has 10 Samsung cell phones but he started the day with 14 Samsung cell phones. Then he notices that he has 5 iPhones and in the initial inventory, but started with 8. His staff then told him that in the afternoon they realized that 2 Samsung cell phones were damaged and 1 iPhone had a manufacturing defect in the screen, so they threw these out during the day. What was the total number of cell phones that were sold today?
Answer: The actual initial inventory of Samsung cell phones was 14, but there were 2 defective phones so 14 - 2 = 12 is the initial inventory of working Samsung phones. The actual initial inventory of iPhone cell phones was 8, but there was one defective phone, so 8 - 1 = 7 is the actual initial inventory of working iPhones. Thus only 12 - 10 = 2 Samsung cell phones were sold. Thus only 7 - 5 = 2 iPhones were sold. Thus the total number of phones sold is 2 Samsung + 2 iPhone = 4 cell phones. The answer is 4.
[Question]Amber buys 7 guppies for her pond. Several days later, she sees 3 dozen baby guppies swimming around. Two days after that, she sees 9 more baby guppies. How many guppies does she have now?
[Answer]3 dozen baby guppies make 3 x 12 = 36 baby guppies. There are a total of 36 + 9 = 45 baby guppies. Adding the adult guppies, there are 7 + 45 = 52 guppies. The answer is 52.
Q: Danny has a huge fish tank that contains 94 guppies, 76 angelfish, 89 tiger sharks, and 58 Oscar fish. If he sells 30 guppies, 48 angelfish, 17 tiger sharks, and 24 Oscar fish. How many fish will remain?
A: There were 94 + 76 + 89 + 58 = 317 fishes in the tank. The fish to be sold is 30 + 48 + 17 + 24 = 119. Therefore, Danny will be left with 317 - 119 = 198 fishes. The answer is 198.
Question: Robby, Jaylen and Miranda are employed at a Cheesecake factory, earning $10 per hour. They work 10 hours a day, five days a week. Robby saves 2/5 of his salary, Jaylene saves 3/5 of his salary, while Miranda saves half of her salary. What are the combined savings of the three employees after four weeks?
Answer: In a day, each of them earns $10 / hour * 10 hours / day = $100 / day. The total number of days each of them work in a month is five days per week * 4 weeks = 20 days. If each of them earns $100 per day, in 20 days, they'll earn 20 days / month * $100 / day = $2000 / month. Robby saves 2 / 5 * $2000 = $800 from his salary. Jaylene's savings is 3 / 5 * $2000 = $1200 of her salary. Miranda saves 1 / 2 * $2000 = $1000 from her salary. The total saving for the three employees is $1000 + $1200 + $800 = $3000. The answer is 3000.
Q: John drinks 2 energy drinks. 1 of them is a 12-ounce drink with 250 grams of caffeine. The second drink is 3 times more caffeinated per ounce but only 2 ounces. He then takes a caffeine pill that has as much caffeine as his 2 drinks combined. How much caffeine did he consume?
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.

The second drink was 2 / 12 = 1 / 6 the size of the first drink. So it had 1 / 6 * 3 = 1 / 2 the caffeine. That means it had 1 / 2 * 250 = 125 grams of caffeine. So the total amount of caffeine he drank was 125 + 250 = 375 grams. So he consumed 375 * 2 = 750 grams of caffeine for the day. The answer is 750.
