Answer this question:Last year, the school library purchased 50 new books. This year, it purchased 3 times as many books. If the library had 100 books before it purchased new books last year, how many books are in the library now?
Last year, there were a total of 100 + 50 = 150 books in the library. The library purchased 50 x 3 = 150 books this year. Therefore, the library now has a total of 150 + 150 = 300 books.
The answer is 300.

Answer this question:Anna goes trick-or-treating in a subdivision where she gets 14 pieces of candy per house. Her brother Billy goes trick-or-tricking in a neighboring subdivision where he gets 11 pieces of candy per house. If the first subdivision has 60 houses and the second subdivision has 75 houses, how many more pieces of candy does Anna get?
First find the total number of pieces of candy Anna gets: 14 pieces / house * 60 houses = 840 pieces. Then find the total number of pieces of candy Billy gets: 11 pieces / house * 75 houses = 825 pieces. Then subtract the number of pieces Billy gets from the number Anna gets to find the difference: 840 pieces - 825 pieces = 15 pieces.
The answer is 15.

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 is 49.
