Q: There are 15 students in the art club. By the end of each quarter, each student makes two artworks. If there are four quarters in a school year, how many artworks can the art club collect in two school years?
A: 15 x 2 = 30 artworks can be collected in one quarter. So in one school year, a total of 30 x 4 = 120 artworks can be collected. Therefore, 120 x 2 = 240 artworks can be collected in two school years. The answer is 240.
Question: Musa is the class teacher of a class of 45 students. He wants to split them into three groups by age. If a third of the class is under 11 years, and two-fifths are above 11 but under 13, how many students will be in the third group (13 years and above)?
Answer: The first group is a third of the class which is (1 / 3) * 45 = 15 students. There are 15 students in the first group, so there are 45 - 15 = 30 students. The second group is two - fifths of the class which is (2 / 5) * 45 = 18 students. There are 18 in the second group so there are 30 - 18 = 12 students left in the third group. The answer is 12.
[Question]Emily goes fishing and has a very busy day. She catches 4 trout, 3 catfish, and 5 bluegills. If the trout weigh 2 pounds each, the catfish weigh 1.5 pounds each, and the bluegills weigh 2.5 pounds each, how many total pounds of fish did she catch?
[Answer]She caught 8 pounds of catfish because 4 x 2 = 8. She caught 4.5 pounds of catfish because 3 x 1.5 = 4.5. She caught 7.5 pounds of bluegill because 5 x 2.5 = 12.5. She caught 20 pounds of fish because 8 + 4.5 + 12.5 = 25. The answer is 25.
Q: Amaya is watching a movie that she finds kind of boring, so she keeps tuning out and having to rewind it to catch what she missed. She watches 35 minutes before she realizes she needs to rewind the movie to catch something she missed, a process that adds 5 minutes to her total viewing time. She watches the movie for another 45 minutes but has to rewind it again, adding 15 minutes to her total time. Finally, she watches the last 20 minutes uninterrupted. If she added up the duration of the film plus all the times she had to rewind and re-watch parts, how many minutes did it take her to watch the movie?
A: Amaya watches the movie without rewinding for 20 minutes + 15 minutes + 45 minutes + 20 minutes = 100 minutes duration of the movie. However, Amaya also spent extra time re - watching parts she rewound, for 5 minutes + 15 minutes = 20 minutes. In all, Amaya spent 100 minutes + 20 minutes = 120 minutes watching the movie. The answer is 120.
Question: Anna's mom gave her $10.00 to buy anything she wanted from the candy store. Anna bought 3 packs of chewing gum for $1.00 each, 5 chocolate bars at $1 each and 2 large candy canes for $0.50 each. How much money did Anna have left?
Answer:
Anna bought 3 packs of chewing gum that were $1 each for a total of 3 * 1 = $3. Anna bought 5 chocolate bars that were $1 each for a total of 5 * 1 = $5. Anna bought 2 large candy canes that were $.50 each for a total of 2 * .50 = $1. The total amount spent was $3 + $5 + $1 = $9.00. Anna had $10 to start and spent $9.00 so she had $10 - $9.00 = $1.00 left. The answer is 1.
