Let R be the number of water bottles Daniel refilled for the rugby team. Daniel filled 11 * 6 = 66 bottles for the football team. He filled 66 + 12 = 78 bottles for the lacrosse team. He got water bottles for four teams, so the team coaches wanted 2 * 4 = 8 bottles. In all, he filled 66 + 53 + 78 + 8 + R = R + 205 = 254 bottles in all. Thus, he filled R = 254 - 205 = 49 bottles for the rugby team this season.
The answer: 49
Reverse engineering the question: Daniel works for a sports stadium filling water bottles for athletes. He filled 254 water bottles this season. The football team had 11 players that wanted 6 bottles each. The soccer team had him fill 53 bottles. The lacrosse team needed 12 more bottles than the football team. Each team coach during the season also wanted two bottles apiece. How many bottles did he fill for the rugby team during the final game he worked this season?


Reasoning and answer: If the bracelets he sold at $5 made $60, he sold $60 / $5 = 12 bracelets. If the total number of $5 bracelets was 12, then the total number of bracelets he sold was 30 - 12 = 18. If he was selling a pair of bracelets at $8, he sold 18 / 2 = 9 pairs. The total amount of money he made from selling the nine pairs is $8 * 9 = $72. His total earnings from selling all of his bracelets are $72 + $60 = $132.
The answer: 132
What was the question?
Question: Zayne sells bracelets for $5 each and two for $8. If he started with 30 bracelets and made $60 from selling bracelets for $5 each, how much in total did he make from selling his bracelets?


Johnny bought 15 packs, and every normal pack has 1 red pencil. He should have 15 * 1 = 15 red pencils. 3 of the packs have 2 extra red colored pencils, so there are 3 * 2 = 6 extra red pencils. In total, Johnny has 15 + 6 = 21 red colored pencils.
The answer: 21
Reverse engineering the question: Johnny buys 15 packs of colored pencils for his class. Each pack has a red, yellow, and green pencil inside. When he gets home he notices that 3 of the packs have two extra red pencils inside. How many red colored pencils did Johnny buy?


Reasoning and answer: Stacie staples 3 x 12 = 36 reports. There are 50 - 36 = 14 staplers left in the stapler.
The answer: 14
What was the question?
Question: There are 50 staplers in the stapler. Stacie staples 3 dozen reports on her desk. How many staplers are left in the stapler?


He lost 220 * .1 = 22 pounds. So after gaining some weight back he was 22 - 2 = 20 pounds lighter than before. So his weight is 220 - 20 = 200 pounds.
The answer: 200
Reverse engineering the question: John weighs 220 pounds when he starts exercising. He manages to lose 10% of his body weight. He then gains back 2 pounds. How much does he weigh at the end?


She splits her $960 profit in half to get $960 / 2 = $480. She receives a total donation of $310, so she now has $310 + $480 = $790. She needed only $610 so she has $790 - $610 = $180 more than she needs.
The answer: 180
Reverse engineering the question:
A trader made a profit of $960 after a week of sales. To raise $610 to pay for her next shipment of wares, she splits the profit in half and solicits donations from her family and friends. If she received a total donation of $310 and adds it to one-half of her profit, how much money did she make above her goal?
