Jen buys and sells candy bars. She buys candy bars for 80 cents each and sells them for a dollar each. If she buys 50 candy bars and sells 48 of them, how much profit does she make in cents?

It costs Jen 80 * 50 =

<<80*50=4000>>4000 cents to buy 50 candy bars. Since a dollar is 100 cents, she earns 48 * 100 = <<48*100=4800>>4800 cents by selling 48 of them. Thus her total profit is 4800 - 4000 = <<4800-4000=800>>800 cents. #### 800 Andrew bought a big bag of balloons. The bag had 303 blue balloons and 453 purple balloons. If Andrew shares half of his balloons with his brother, how many balloons does he have left? There are 303 + 453 = <<303+453=756>>756 balloons in the bag. Once Andrew gives half of his balloons to his brother he has 756/2=<<756/2=378>>378 balloons left. #### 378 Liz roasts 2 16 pounds turkeys every Thanksgiving. She can only roast them 1 at a time because she has a small oven. She roasts each turkey for 15 minutes per pound. If dinner is served at 6:00 pm what is the latest time she can start roasting the turkeys? She bakes a turkey for 15 minutes a pound and the turkey is 16 pounds so it takes 15*16 = <<15*16=240>>240 minutes She has 2 turkeys to roast and one turkey takes 240 minutes to cook so 2 turkeys will take 2*240 = <<2*240=480>>480 minutes There are 60 minutes in an hour and these turkeys will take 480 minutes to cook so that's 480/60 = <<480/60=8>>8 hours In military time, 6:00 pm is 18:00 hours (12 hours +6 hours) and it takes 8 hours to cook the turkeys so the latest she can start is 18- 8 = 10:00 am #### 10 Julia bought 3 packs of red balls, 10 packs of yellow balls, and 8 packs of green balls. There were 19 balls in each package. How many balls did Julie buy in all? The total number of packages is 3 + 10 + 8 = <<3+10+8=21>>21. Julia bought 21 × 19 = <<21*19=399>>399 balls. #### 399 Jessy told eleven jokes this past Saturday, and Alan told seven jokes. If they doubled the number of jokes they told this past Saturday next Saturday, how many jokes would they have told in total together so far? This past Saturday, Jessy and Alan told a total of 11+7 = <<11+7=18>>18 jokes together. Since Jessy told eleven jokes this past Saturday, when he doubles the number of jokes next Saturday, the number of jokes will be 2*11= 22 next Saturday. At the same time, after telling seven jokes this Saturday, when he doubles the number of jokes next Saturday, Alan will tell 2*7 = <<2*7=14>>14 jokes. Next Saturday, they will tell 14+22 = <<14+22=36>>36 jokes together. In total, the number of jokes will be 36+18 = <<36+18=54>>54 jokes on the two Saturdays. #### 54 The moon has a surface area that is 1/5 that of Earth. The surface area of the Earth is 200 square acres. The land on the moon is worth 6 times that of the land on the Earth. If the total value of all the land on the earth is 80 billion dollars, what is the total value in billions of all the land on the moon? If the moon land had the same value as earth land it would be worth 16 billion because 80 / 5 = <<80/5=16>>16 The moon's total land value is 96 billion because 16 x 6 = <<16*6=96>>96 #### 96 Dikembe wants to teach everyone at school about the importance of flossing, so he plans to bring enough packets of floss for everyone. There are 20 students in his class. Each student needs 1.5 yards of floss. He sees in the store that each packet of floss contains 35 yards. If he buys the least amount necessary, how much floss is left over? He will need to bring 30 yards of floss because 20 x 1.5 = <<20*1.5=30>>30 One packet of floss is enough because 35 > 30 He has 5 yards left over because 35 - 30 = <<35-30=5>>5 #### 5 Jade is building a lego tower. She has 100 pieces. Each level has to be 7 pieces wide. If she has 23 pieces left at the end, how many levels is her tower? She used 77 legos because 100 - 23 = <<100-23=77>>77 She made 11 levels because 77 / 7 = <<77/7=11>>11 #### 11 Davonte is trying to figure out how much space his art collection takes up. He measures his paintings and finds he has three square 6-foot by 6-foot paintings, four small 2-foot by 3-foot paintings, and one large 10-foot by 15-foot painting. How many square feet does his collection take up? His square paintings take up 36 square feet each because 6 x 6 = <<6*6=36>>36 His small paintings take 6 square feet each because 2 x 3 = <<2*3=6>>6 His large painting takes up 150 square feet because 10 x 15 = <<10*15=150>>150. Combined, his square paintings take up 108 square feet because 3 x 36 = <<3*36=108>>108 Combined, his small paintings take up 24 square feet because 4 x 6 = <<4*6=24>>24 In total, his paintings take up 282 square feet because 150 + 108 + 24 = <<150+108+24=282>>282 #### 282 Pablo’s mother agrees to pay him one cent for every page he reads. He plans to save the money for some candy. Pablo always checks out books that are exactly 150 pages. After reading his books, he went to the store and bought $15 worth of candy and had $3 leftover. How many books did Pablo read? He gets $1.5 per book because .01 x 150 = <<.01*150=1.5>>1.5 He earned $18 because 15 + 3 = <<15+3=18>>18 He read 12 books because 18 / 1.5 = <<18/1.5=12>>12 #### 12
