Q: A movie that's 1.5 hours long is being replayed 6 times in one movie theater each day. There is a 20-minute advertisement before the start of the movie. How long, in hours, does the movie theater operate each day?
A: The movie that is being replayed 6 times takes 1.5 x 6 = 9 hours. The advertisements before the start of the movie take 20 x 6 = 120 minutes in all. One hundred twenty minutes is equal to 120 / 60 = 2 hours. Thus, the movie theater operates for 9 + 2 = 11 hours each day. The answer is 11.
Question: John has to restring 3 basses with 4 strings each, twice as many guitars which have 6 strings each, and 3 fewer 8 string guitars than the normal guitars. How many strings does he need?
Answer: The basses take 3 * 4 = 12 strings. He restrings 2 * 3 = 6 normal guitars. That takes 6 * 6 = 36 strings. He restrings 6 - 3 = 3 guitars with 8 strings. So that uses 3 * 8 = 24 strings. So he uses 12 + 36 + 24 = 72 strings. The answer is 72.
[Question]Jordan gave Danielle two dozen roses and a box of chocolates as a birthday day gift. Later that day, after Jordan left, Danielle traded the box of chocolates for another dozen roses. Overnight, half of the roses wilted, and Danielle decided to throw the wilted flowers away. On the second day, another half of the remaining flowers wilted, and she threw the wilted ones away. How many unwilted flowers remained?
[Answer]Danielle started with two dozen roses, or a total of 2 * 12 = 24 roses. Her trade added another dozen roses, for a total of 12 + 24 = 36 roses. The first night, half of the roses wilted, leaving 36 / 2 = 18 roses. On the second night, again half of the remaining roses wilted, leaving 18 / 2 = 9 unwilted roses. The answer is 9.
Q: A jewelry box has 10 necklaces and 15 earrings. Jessy goes to the jewelry stores and buys 10 more necklaces and 2/3 as many earrings as before. After returning home, her mother gives her 1/5 times more earrings than the number she purchased at the store. Calculate the total number of jewelry pieces Jessy has in her box if she puts all of them together.
A: The total number of jewelry Jessy had before going to the store is 10 necklaces + 15 earrings = 25. At the store, Jessy bought 2 / 3 * 15 = 10 earrings. When she got back from the store, Jessy received 1 / 5 * 10 = 2 more earrings than the ones she bought at the store from her mother. The total number of earrings Jessy received from her mother is 2 + 10 = 12 earrings. The total number of earrings Jesy has after being given 12 more from her mother is 10 + 12 = 22 earrings outside the jewelry box. When Jessy puts all the jewelry in the box, the total number becomes 22 new earrings + 10 new necklaces + 25(the total number of jewelry she had before) = 57. The answer is 57.

Q: Jeff is collecting matchbox cars. He has twice as many cars as trucks. He has 60 total vehicles. How many trucks does he have?
