Q: Luke started working on a 1000-piece jigsaw puzzle. The first day he worked on it, he put together 10% of the pieces. On the second day, he put together another 20% of the remaining pieces from the first day. On the third day, he put together 30% of the remaining pieces from the previous day. How many pieces does he have left to complete after the third day?
A: Luke started putting together, 1000 x 0.1 = 100 pieces. The next day, there were 1000 - 100 = 900 pieces left. Then he put together 900 * 0.2 = 180 pieces on the second day. So there were 900 - 180 = 720 pieces left. On the third day, he put together 720 * 0.3 = 216 pieces. Therefore, Luke still has 720 - 216 = 504 pieces left to complete the puzzle. The answer is 504.
Question: 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?
Answer: 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]Donna worked 2 hours every morning walking dogs in her neighborhood for $10.00 an hour. 5 days a week, after school, she worked at a card shop for 2 hours and made $12.50 an hour. On the weekends, she usually made $10.00 an hour babysitting and was guaranteed 4 hours every Saturday from her neighbor. How much money did she make over 7 days?
[Answer]She makes $10.00 an hour for 2 hours walking dogs so she makes 10 * 2 = $20.00 every morning. Over 7 days she makes 7 * 20 = $140.00 a week. She makes $12.50 for 2 hours working at a card shop so she makes 12.5 * 2 = $25.00. She works there 5 days a week so she makes 5 * 25 = $125.00 a week. She also babysits for 4 hours making $10.00 an hour for a total of 4 * 10 = $40.00. Over 7 days, she makes 140 + 125 + 40 = $305.00. The answer is 305.
Q: In a day, Sam hunts 6 animals. Rob hunts half as many animals as Sam. Mark hunts 1/3 of the total of what Rob and Sam hunt. If Peter hunts 3 times as many animals as Mark does, how many animals do they all hunt in a day?
A: Rob hunts 1 / 2 * 6 animals / day = 3 animals / day. Rob and Sam hunt 3 animals / day + 6 animals / day = 9 animals / day. Mark hunts 1 / 3 * 9 animals / day = 3 animals in a day. Peter hunts 3 * 3 animals / day = 9 animals in a day. The total they all hunt in a day is 6 animals / day + 3 animals / day + 3 animals / day + 9 animals / day = 21 animals. The answer is 21.
Question: Ursula bought five hot dogs at $1.50 each and three salads at $2.50 each. If she had two $10 bills, how much change did she get back?
Answer: Five hotdogs cost 5 x $1.50 = $7.50. Three salads cost 3 x $2.50 = $7.50. The total cost was $7.50 + $7.50 = $15. And, Ursula had 2 x $10 = $20. Therefore, Ursula got a change of $20 - $15 = $5. The answer is 5.
Q: A dog barks 30 times per minute. If 2 dogs bark 30 times per minute, how many times will they have barked after 10 minutes?
A:
There are 2 dogs and they each bark 30 times per minute so together they bark 2 * 30 = 60 times per minute. 2 dogs bark a combined total of 60 times per minutes, after 10 minutes they will have barked 60 * 10 = 600 times. The answer is 600.
