Question: John buys 3 puzzles. The first puzzle has 1000 pieces. The second and third puzzles have the same number of pieces and each has 50% more pieces. How many total pieces are all the puzzles?
Answer: The second puzzle has 1000 * .5 = 500 more pieces than the first. So it has 1000 + 500 = 1500 total pieces. That means those two puzzles have 1500 * 2 = 3000 pieces. So in total there were 3000 + 1000 = 4000 pieces. The answer is 4000.
[Question]During a unit on probability, a teacher surveys her class asking her students two questions. The first question was whether they prefer dogs or cats, and the second question was whether they movies or video games. Of the 30 students in her class, 50% chose dogs and video games as their two answers, while 10% chose dogs and movies as their two answers. In total, how many students in this teacher's class prefer dogs over cats?
[Answer]The 50% of the class that chose dogs and video games amounts to 30 * 0.5 = 15 students who prefer dogs over cats. Similarly, the 10% that chose dogs and movies amount to 30 * 0.1 = 3 students who prefer dogs over cats. Because these are the only two ways that a student could indicate their preference for dogs, and because these groups do not overlap, a total of 15 + 3 = 18 students favor dogs over cats in this teacher's class. The answer is 18.
Q: Abraham is buying some toiletries and creates a budget of $60 for his shopping. He buys 4 shower gels for $4 each, a tube of toothpaste for $3, and a box of laundry detergent. If he has $30 remaining in his budget, how much money, in dollars, did Abraham spend on the box of laundry detergent?
A: Shower gel costs Abraham 4 shower gels * $4 = $16. So the shower gel and toothpaste combined have cost him $16 + $3 = $19. He had money remaining in his budget so the total cost of his shopping must have been $60 – $30 = $30. The box of laundry detergent therefore cost him $30 – $19 = $11. The answer is 11.
Question: Claudia offers art classes to kids and charges $10.00 for her one-hour class. If 20 kids attend Saturday’s class and half that many attend Sunday’s class, how much money does she make?
Answer: Sunday’s class is half the size of Saturday’s class with 20 kids so Sunday has 20 / 2 = 10 kids. She has 20 kids on Saturday and 10 kids on Sunday for a total of 20 + 10 = 30 kids. She charges $10.00 per kid and teaches 30 kids over the weekend so she makes 10 * 30 = $300.00. The answer is 300.
[Question]To get clean, Michael takes a bath twice a week and a shower once a week. How many total times does he clean himself in 52 weeks, which is about one year?
[Answer]Michael cleans himself 3 times a week because 2 + 1 = 3. He cleans himself 156 times 52 weeks because 52 x 3 = 156. The answer is 156.
[Question]While passing by a store, Miley noticed that a bag that cost $150 last week is now on sale for $135. What percent is the discount?
[Answer]
The bag is now sold for $150 - $135 = $15 less. The discount is 15 / 150 = 1 / 10. Thus, the percent discount is 1 / 10 x 100% = 10%. The answer is 10.
