Question: Pablo likes to put together jigsaw puzzles. He can put together an average of 100 pieces per hour. He has eight puzzles with 300 pieces each and five puzzles with 500 pieces each. If Pablo only works on puzzles for a maximum of 7 hours each day, how many days will it take him to complete all of his puzzles?
Answer: First find how many pieces are total in each puzzle. 8 puzzles * 300 pieces each = 2400 pieces. Next, 5 puzzles * 500 pieces each = 2500 pieces. All of the puzzles have 2400 pieces + 2500 pieces = 4900 pieces total. He will work a maximum of 7 hours each day * 100 pieces per hour = 700 pieces per day. So he will end up taking 4900 pieces total / 700 pieces per day = 7 days total. The answer is 7.
[Question]Philip has a farm with animals. He has 20 cows, 50% more ducks. Philip also has as many pigs as one-fifth of ducks and cows in total. How many animals does Philip have on his farm?
[Answer]Philip has 50 / 100 * 20 = 10 more ducks than cows. Which means he has 20 + 10 = 30 ducks. So Philip's cows and ducks sum up to 20 + 30 = 50 animals. If there are 50 cows and ducks, that means Philip has 1 / 5 * 50 = 10 pigs. In total Philip has 50 + 10 = 60 animals on his farm. The answer is 60.
Q: Mrs. Dunbar was creating floral arrangements for her niece's wedding. She needed to make 5 bouquets and 7 table decorations. She uses 12 white roses in each table decoration and 5 white roses in each bouquet. How many white roses in total does she need to complete all bouquets and table decorations?
A: For table arrangements, she needs 7 * 12 = 84 white roses. For bouquets, she needs 5 * 5 = 25 white roses. Thus, in total, she needs 84 + 25 = 109 white roses. The answer is 109.
Question: Yvonne brings a box of chocolates to school. Half have nuts and half do not. The students eat 80% of the ones with nuts and eat half of the ones without nuts. If there are 28 chocolates left, how many chocolates were in the box?
Answer: The ones with nuts that they ate was 40% of the box because 80% x .5 = 40%. The ones without nuts that they ate equaled 25% of the box because 50% x .5 = 25%. They ate 65% of the box because 40 + 25 = 65. They left 35% of the box because 100 - 65 = 35. The box had 80 chocolates because 28 / .35 = 80. The answer is 80.
Q: Rob planned on spending three hours reading in preparation for his literature exam. If he ends up spending only three-quarters of this time reading, and he reads a page every fifteen minutes, how many pages did he read in this time?
A:
1 hour is 60 minutes so 3 hours is 3 * 60 = 180 minutes. Three - quarters of 180 minutes is (3 / 4) * 180 = 135 minutes. He spends 15 minutes on 1 page so he will spend 135 minutes on 135 / 15 = 9 pages. The answer is 9.
