[Question]Sandra has a box of apples that weighs 120 pounds. She's going to use half the weight in apples to make applesauce. The rest will be used to make apple pies. She needs 4 pounds of apples per pie. How many pies will she be able to make?
[Answer]The box weighs 120 pounds and she's going to use half of it to make applesauce so she'll use 120 / 2 = 60 pounds for applesauce. The box weighs 120 pounds and she'll use 60 pounds for applesauce so that leaves 120 - 60 = 60 pounds of apples. She has 60 pounds of apples and she needs 4 pounds to make a pie so she can make 60 / 4 = 15 pies. The answer is 15.
Q: John's shirt cost 60% more than his pants. His pants cost $50. How much was John's outfit?
A: John's pants cost 50 * .6 = $30 more than his pants. So his shirt cost 50 + 30 = $80. So in total he spent 80 + 50 = $130. The answer is 130.
Question: Students at Highridge High earn 2 points for each correct answer during a quiz bowl If a student correctly answers all the questions in a round, the student is awarded an additional 4 point bonus. They played a total of five rounds each consisting of five questions. If James only missed one question, how many points did he get?
Answer: If James only missed one question in all five rounds of five questions, he correctly answered 5 * 5 - 1 = 24 questions. Before the bonus, James earned 24 correct answers * 2 points / answer = 48 points. Since missing one question would only disqualify him from receiving a bonus in one round, he would earn a bonus for 5 - 1 = 4 rounds. He should expect a bonus of 4 rounds * 4 points / round = 16 points. Including his bonus, James scored a total of 48 + 16 = 64 points. The answer is 66.
[Question]Vivian plays 10 Spotify songs every day. Her best friend Clara plays 2 fewer songs each day. If in June they didn't play any song during the weekends only, and there were 8 weekend days in June, what's the total number of songs they both listened to in that month?
[Answer]June has 30 days, so if they didn't play any songs on weekends, then they played 30 days - 8 days = 22 days. If Vivian played 10 songs each day, the total number of songs she played for the month is 10 songs / day * 22 days = 220 songs. Clara played 2 fewer songs, which is 10 songs / day - 2 songs / day = 8 songs / day. The total number of songs played by Clara for the whole month is 8 songs / day * 22 days = 176 songs. The total played by both is 220 songs + 176 songs = 396 songs. The answer is 396.

Two pairs of sunglasses costs 2 x $50 = $100. So, Mary spent $100 + $100 = $200. Thus, two decks of basketball cards costs $200 - $150 = $50. Therefore, one deck of basketball cards costs $50 / 2 = $25. The answer is 25.
