Mary had 89 stickers. She used 3 large stickers on the front page of her journal and 7 stickers each to 6 other pages of her journal. How many stickers does Mary have remaining?

Mary added a total of 7 stickers/page * 6 pages=

<<7*6=42>>42 stickers to the 6 other pages. In total, Mary added 3 large stickers + 42 stickers = <<3+42=45>>45 stickers to her journal. Since she started with 89 stickers, she now has 89 - 45 = <<89-45=44>>44 stickers left. #### 44 Beckett is 12 and is three years younger than Olaf, while Shannen is two years younger than Olaf. If Jack is five more than twice as old as Shannen, what is the sum of the ages of all 4 people? Olaf is 12 years + 3 years = <<12+3=15>>15 years old. Shannen is 15 years old - 2 years = <<15-2=13>>13 years old. Jack is 5 years + (2 * 13 years) = <<5+(2*13)=31>>31 years old. The sum of all of their ages is 12 + 15 + 13 + 31 = <<12+15+13+31=71>>71 years old. #### 71 To pass the time while she is waiting somewhere Carla likes to count things around her. While she is waiting for school to start on Monday she counts the tiles on the ceiling--38. While she is waiting for everyone to finish their tests after she has handed in hers, she counts the books in the room--75. On Tuesday Carla counts all the tiles twice in a row and she counts the books three times in a row when she has to wait for a long time for the teacher to finish handing out the graded tests. If every time Carla counts something counts as once, how many times has Carla counted something on Tuesday? When Carla was waiting on Monday she counted 38 ceiling tiles and on Tuesday she counted them twice, 38 ceiling tiles x 2 = <<38*2=76>>76 times she counted a ceiling tile. She also counted 75 books in the room on Monday and counted them three times in a row on Tuesday, 75 books x 3 = <<75*3=225>>225 times she counted a book. On Tuesday Carla counted the ceiling tiles 76 times + counted books 225 times = <<76+225=301>>301 times Carla counted something on Tuesday. #### 301 Martha is making centerpieces for her Thanksgiving dinner. There are six centerpieces, and each centerpiece uses 8 roses, twice as many orchids as roses, and a certain number of lilies. If Martha wants to spend $2700 total, and each flower costs $15, how many lilies will she put in each centerpiece? First figure out how many total flowers Martha is going to buy by dividing her total spending by the price per flower: $2700 / $15/flower = <<2700/15=180>>180 flowers Now figure out how many flowers are in each centerpiece by dividing the total number of flowers by the number of centerpieces: 180 flowers / 6 centerpieces = <<180/6=30>>30 flowers / centerpiece Now figure out how many orchids are in each centerpiece by multiplying the number of roses per centerpiece by 2: 8 roses/centerpiece * 2 = <<8*2=16>>16 orchids/centerpiece Now subtract the number of roses and orchids per centerpiece from the total number of flowers per centerpiece to find the number of lilies per centerpiece: 30 flowers - 16 orchids - 8 roses = <<30-16-8=6>>6 lilies #### 6 Nine hundred tickets were sold to a concert. Three-fourths of those who bought the ticket came before the start of the concert. Five-ninths of the remaining came few minutes after the first song. Eighty people arrived during the middle part of the concert while the rest did not go. How many of those who bought the tickets did not go? 900 x 3/4 = <<900*3/4=675>>675 people came before the start of the concert. 900 - 675 = <<900-675=225>>225 people did not come before the start of the concert. 225 x 5/9 = <<225*5/9=125>>125 people came few minutes after the first song. So, 125 + 80 = <<125+80=205>>205 people came to the concert that was not able to be at the start of the concert. Therefore, 225 - 205 = <<225-205=20>>20 people did not go to the concert. #### 20 Gina had $400. She gave 1/4 of her money to her mom, used 1/8 of her money to buy clothes, gave 1/5 of her money to a charity, and kept the remaining money. How much did Gina keep? Gina's mom received 1/4 x $400 = $<<1/4*400=100>>100. She used 1/8 x $400 = $<<1/8*400=50>>50 to buy clothes. She gave 1/5 x $400 = $<<1/5*400=80>>80 to a charity. Thus, she spent a total of $100 + $50 + $80 = $<<100+50+80=230>>230. Therefore, Gina kept $400 - $230 = $<<400-230=170>>170. #### 170 The difference between the ages of two friends is 2 years. The sum of their ages is 74 years. Find the age of the older friend. Let X be the age of the older friend. The younger friend is X-2 years old. So, the age of both is X + (X-2) = 74. X + X = 74 + 2. 2 * X = 76. Then, the older friend is X = <<38=38>>38 years old. #### 38 Roman the Tavernmaster has $20 worth of gold coins. He sells 3 gold coins to Dorothy. After she pays him, he has $12. How many gold coins does Roman have left? Dorothy paid $12 for 3 gold coins so each gold coin is worth $12/3 = $<<12/3=4>>4 The Tavern master originally had $20 worth of gold coins which is $20/$4 = <<20/4=5>>5 gold coins He gave 3 out of 5 gold coins to Dorothy so he now has 5-3 = <<5-3=2>>2 gold coins left #### 2 Anton has three times as many cards in his collection as Heike does. Ann has six times as many cards as Heike does. If Ann has 60 cards, how many more cards does Ann have more than Anton? If Ann has 60 cards, which is six times as many cards as Heike, Heike has 60/6= <<60/6=10>>10 cards. Anton has three times as many cards in his collection as Heike does, and since Heike has 10 cards, Anton has 10*3=<<3*10=30>>30 cards. Ann has 60-30=<<60-30=30>>30 more cards than Anton. #### 30 Annie is a mother of 3 children: Mark, Matt, and Mike. She decided to give them some fruits. Mike received 3 oranges. Matt got twice as many apples, and Mark got as many bananas as Mike and Matt received fruits altogether. How many fruits do the three children have in total? Mike received 3 oranges. Matt received twice as many apples as Mike received oranges, so he got 3 * 2 = <<3*2=6>>6 apples. Mark received 6 + 3 = <<6+3=9>>9 bananas. So in total, all children received 3 + 6 + 9 = <<3+6+9=18>>18 fruits. #### 18
