Q: 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?
A: 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: Anahi bought a 500 pages book to write some notes on. In the first week, she wrote on 150 pages. In the second week, she wrote on 30% of the remaining pages. While continuing writing, she accidentally spilled coffee on the book and damaged 20 percent of the empty pages she was to write on. Calculate the total number of empty pages available for her to write on now.
Answer: If she bought a 500 pages book and wrote on 150 pages, the number of empty pages remaining is 500 - 150 = 350 pages. She then wrote on 30% of the remaining empty pages on the second week, a total of 30 / 100 * 350 = 105 pages. The number of remaining empty pages is 350 - 105 = 245 pages. When she spilled coffee on the remaining empty pages, the number of damaged pages was 20 / 100 * 245 = 49. The number of empty pages remaining that she could write on is 245 - 49 = 196 pages. The answer is 196.
[Question]Crystal wanted to sell everything left in her pastry class before closing for the night. She reduced her $3.00 cupcakes and her $2.00 cookies by half. How much money did she make if she sold the last 16 cupcakes and 8 cookies?
[Answer]She reduced the price of the $3.00 cupcakes by half so they are now 3 / 2 = $1.50. She reduced the price of the $2.00 cookies by half so they are now 2 / 2 = $1.00. She sold 16 cupcakes at $1.50 each so she made = 16 * 1.50 = $24.00. She sold 8 cookies at $1.00 each so she made 8 * 1 = $8.00. She made $24.00 from the cupcakes and $8.00 from the cookies for a total of 24 + 8 = $32.00. The answer is 32.
Q: Jeff was driving to the capital city to attend a conference. At first, he was driving at 80 miles/hour for about 6 hours, then the speed limit changed and he had to slow down to 60 miles/hour, and so he drove at this speed for 4 hours. Then he made a stop at a gas station. Once the car was full of gas, he drove at 40 miles/hour the rest of the trip for 2 hours. How many miles did he travel?
A: In the first stretch he drove 80 miles / hour x 6 hours = 480 miles. In the second stretch he drove 60 miles / hour x 4 hours = 240 miles. After the gas station he drove 40 miles / hour x 2 hours = 80 miles. In total he drove 480 miles + 240 miles + 80 miles = 800 miles. The answer is 800.
Question: The total distance between 2 towns is 200 miles. Roger and his friend drove 1/4 of the total distance, taking 1 hour to do so. They take lunch for another 1 hour and then drove the remaining distance going at the same speed as before. What's the total amount of time, in hours, Roger and his friend took to travel between the two towns?
Answer: When they covered 1 / 4 of the total distance, they were 1 / 4 * 200 = 50 miles away from the starting point. The total distance remaining is 200 - 50 = 150 miles. If they took 1 hour to travel 50 miles, their speed was 50 / 1 = 50 miles per hour. If Roger was driving at 50 miles per hour, then the total time it took him to travel 150 miles is 150 / 50 = 3 hours. The total amount of time taken for the whole journey is 3 + 1 + 1 = 5 hours. The answer is 5.
Q: A store offers a $2 discount for every $10 purchase on any item in the store. Kataleya went to the store and bought 400 peaches sold at forty cents each. Calculate the total amount of money she paid at the store for the fruits.

The total cost for the peaches was 400 * $0.40 = $160. The total count of 10 dollar purchases Kataleya received a discount on was $160 / $10 = 16. If each purchase had a $2 discount, the total discount she received is 16 * $2 = $32. She purchased the peaches at $160 - $32 = $128. The answer is 128.
