Q: The bakery makes 3 batches of baguettes a day. Each batch has 48 baguettes. After the first batch came out, he sold 37. After the second batch, he sold 52. After the third batch he sold 49. How many baguettes are left?
A: He makes 3 batches of baguettes a day, 48 per batch so he makes 3 * 48 = 144. He sells 37, then 52 then 49 baguettes for a total of 37 + 52 + 49 = 138. He had 144 to sell and he sold 138 so he has 144 - 138 = 6 left over. The answer is 6.
Question: A water tank has a capacity of 4000 gallons. Mack connects a pipe to the tank that fills the tank with water at the rate of 10 gallons per hour. How long will it take to fill the tank to 3/4 of its capacity?
Answer: 3 / 4 of the water tank is 3 / 4 * 4000 = 3000. If the pipe fills the tank with water at the rate of 10 gallons per hour, it will take 3000 / 10 = 300 hours to fill the tank to 3 / 4 of its capacity. The answer is 300.
[Question]Jimmy needs to score at least 50 points to pass to the next class. He earned 20 points for each of the 3 exams he wrote but lost 5 points during the school year for bad behavior. How many more points can Jimmy lose and still be able to pass the next class?
[Answer]Jimmy earned 20 * 3 = 60 points for the exams he wrote. For bad behavior, he lost 5 points, so he has 60 5 = 55 points left. To pass to the next class, Jimmy needs at least 50 points, so he can lose 55 50 = 5 more points. The answer is 5.
Q: A trolley driver picked up 10 people on his 1st stop. On the next stop, 3 people got off and twice as many people from the 1st stop got on. On the third stop, 18 people got off and 2 got on. How many people are currently on the trolley?
A: Between the trolley driver and his first 10 customers, there are 1 + 10 = 11 people are currently on the trolley. On his first stop, 10 people go on and twice as many people got on at the second stop so 10 * 2 = 20 people got on at the second stop. So at the second stop he had 11 people on board, 3 got off and 20 got on so he now has 11 - 3 + 20 = 28 people. At his third stop 18 people got off and 2 got on so in total there are 28 - 18 + 2 = 12 people on the trolley. The answer is 12.
Question: A citrus grove has laid out their plans for their sixteen orchards for the growing season. Lemons, their most popular citrus fruit, will take up eight orchards. Oranges are their second most popular fruit and will occupy half as many orchards as the lemons. Limes and grapefruits will split the remaining orchards. How many citrus orchards will be growing grapefruits?
Answer: Oranges will occupy 8 / 2 = 4 orchards. There will be 16 - 8 - 4 = 4 orchards remaining for limes and grapefruits. Thus, 4 / 2 = 2 orchards will be growing grapefruits. The answer is 2.
Q: Noel bakes 4 dozen donuts for his class. There are 30 students in class, but only 80% like donuts. How many donuts does each student who likes donuts get to eat?
