Q: At a laundromat, it costs $4 for a washer and a quarter for every 10 minutes in the dryer. Samantha does 2 loads of laundry in the wash and then divides all the washed clothes equally into 3 separate dryers. If she lets the dryers run for 40 minutes each, how much does she spend altogether?
A: Samantha spends $4 x 2 = $8 on washing. Each dryer costs 25 x 4 = 100 cents = $1. Three dryers cost 1 x 3 = $3. Altogether, she spends 8 + 3 = $11. The answer is 11.
Question: Elsa started the day with 40 marbles. At breakfast, she lost 3 marbles while playing. At lunchtime, she gave her best friend Susie 5 marbles. In the afternoon, Elsa's mom bought her a new bag with 12 marbles. Susie came back and gave Elsa twice as many marbles as she received at lunch. How many marbles did Elsa end the day with?
Answer: Elsa had 40 marbles - 3 - 5 = 32 marbles. Elsa then gained 12 marbles + 32 = 44 marbles. At dinner Elsa received 2 * 5 marbles from Susie = 10 marbles. In total Elsa had 44 marbles + 10 = 54 marbles. The answer is 54.

Q: Keaton has a farm of oranges and apples. He can harvest his oranges every 2 months and can sell the harvest for $50. He can harvest his apples every 3 months and can sell this harvest for $30. How much money can Keaton earn every year?
A: Keaton can harvest his oranges every year is 12 / 2 = 6 times. So the total money he earns for his oranges every year is $50 x 6 = 300. He can harvest his apples 12 / 3 = 4 times in a year. So the total money he earns for the apple in a year is $30 x 4 = 120. Therefore, the total money he earns for his oranges and apples is $300 + $120 = $420. The answer is 420.
Question: A fifth-grade class went on a field trip to the zoo, and their class of 10 students merged with another class with the same amount of students. 5 parents offered to be a chaperone, and 2 of the teachers from both classes will be there too. When the school day was over, the students could choose to go home and 10 of them left. Two of the chaperones were parents in that group, so they left as well. How many individuals were left at the zoo?
Answer: A total of 10 * 2 = 20 students went on the field trip. Some chaperones showed up, letting the group grow to 20 + 5 = 25 individuals. The teachers had to come as well, making the group as big as 25 + 2 = 27 individuals. When the school day ended, 27 - 10 = 17 individuals were left. A couple of chaperones followed suit, leaving 17 - 2 = 15 people at the zoo. The answer is 15.
