Q: Andy walks 50 meters from his house to school. After school, he comes back to the house and goes to the market. If he walks 140 meters in total, how many meters is the distance between the house and the market?
A: He walks 50m from home to school and walks 50m again from school to house, so he walks 50m + 50m = 100 meters. If the total distance is 140m, the distance between the house and the market is 140m - 100m = 40 meters. The answer is 40.
Question: Lisa bought a new iPhone for $1000. She bought a phone contract that costs $200/month, a case that costs 20% of the cost of the phone, and headphones that cost half as much as the case. How much will Lisa spend on her phone in the first year?
Answer: First find the cost of the case: $1000 * 20% = $200. Then find the cost of the headphones: $200 / 2 = $100. Then find how much the phone contract will cost over a year: $200 / month * 12 months / year = $2400. Finally, add the cost of the phone, accessories, and plan over the first year to find the total: $2400 + $100 + $200 + $1000 = $3700. The answer is 3700.
[Question]John buys 5 toys that each cost $3. He gets a 20% discount. How much did he pay for everything?
[Answer]The toys cost 5 * 3 = $15. His discount is worth 15 * .2 = $3. So he pays 15 - 3 = $12. The answer is 12.
Q: A book costs $4 more than a CD. The CD is 30% cheaper than a $20 album. How much does the book cost?
A: The CD is 30 / 100 * 20 = $6 cheaper than the album. So the cost of the CD is 20 - 6 = $14. The book is $4 more expensive than the CD, which means it cost 14 + 4 = $18. The answer is 18.
Question: Sarah walked to school carrying a bag containing 25 apples. At school, she gave each teacher she saw an apple. She also gave a single apple to each of 5 of her closest friends. And while she walked home, she also ate one of the apples. If she had three apples left in the bag when she got home, how many apples had she given away to teachers?
Answer: Of her original 25 apples, Sarah gave five to friends, meaning she has no more than 25 - 5 = 20 apples available to give to teachers. She ate one while walking home, meaning she had no more than 20 - 1 = 19 apples available to give to teachers. And since she had three apples remaining when she got home, then the amount she had given to teachers was 19 - 3 = 16 apples. The answer is 16.
Q: A pastry chef is making brownies but is running out of butter. The recipe he is following calls for 2 ounces of butter for every 1 cup of baking mix; however, it allows 2 ounces of coconut oil to be substituted for the 2 ounces of butter if necessary. The chef would like to use as much butter as possible before switching over and substituting coconut oil. If the chef had 4 ounces of butter remaining, and he plans on using 6 cups of baking mix, how many ounces of coconut oil will he end up using?
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.

Every 2 ounces of butter is enough to cover 1 cup of baking mix, so the chef's remaining 4 ounces of butter will be enough to cover 4 / 2 = 2 cups of baking mix. This leaves 6 - 2 = 4 cups of baking mix that will require the use of coconut oil as a substitute. Since each cup of baking mix requires 2 ounces of coconut oil, these 4 cups will require a total of 4 * 2 = 8 ounces of coconut oil. The answer is 8.
