If you buy a dozen of doughnuts, it costs $8; but if you buy 2 dozens, it costs $14. How much will you save from buying 3 sets of 2 dozens than buying 6 sets of 1 dozen?

Six sets of 1 dozen of doughnuts cost $8 x 6 = $

<<6*8=48>>48. Three sets of 2 dozens of doughnuts cost $14 x 3 = $42. Therefore, you can save $48 - $42 = $<<48-42=6>>6. #### 6 Ricciana and Margarita joined in their school's long jump event. Ricciana ran and jumped a total of 24 feet - 20 feet for running and 4 feet for jumping. Margarita ran for 18 feet and jumped 1 foot less than twice Ricciana's jump. How much farther did Margarita run and jump than Ricciana? Twice the distance of Ricciana's jump is 4 x 2 = <<4*2=8>>8 feet. So, Margarita jumped 8 - 1 = <<8-1=7>>7 feet. Margarita ran and jumped for 18 + 7 = <<18+7=25>>25 feet in all. So, Margarita ran and jumped 25 - 24 = <<25-24=1>>1 foott more than Ricciana. #### 1 A carton of ice cream contains 10 scoops each. Mary has 3 cartons of ice cream, one chocolate, one strawberry and one vanilla. Ethan wants one scoop of vanilla and one of chocolate. Lucas, Danny and Connor all want 2 scoops of chocolate. Olivia would like a scoop of vanilla and one of strawberry. Shannon wants twice as much as Olivia. How many scoops of ice cream will be left? The total number of scoops of ice cream that Mary has is 3 cartons * 10 scoops = <<3*10=30>>30 scoops of ice cream. Lucas, Danny and Connor will eat 2 scoops * 3 people = <<2*3=6>>6 scoops of ice cream. Shannon will eat 2 * (1 vanilla + 1 strawberry) = <<2*(1+1)=4>>4 total scoops of ice cream. Combined the kids will eat a total of 2 + 6 + 2 + 4 scoops = <<2+6+2+4=14>>14 scoops of ice cream. Mary will have 30 scoops - 14 scoops = <<30-14=16>>16 scoops of ice cream remaining. #### 16 Adam’s wardrobe is too crowded so he decides to donate some of his clothes to a charity shop. He takes out 4 pairs of pants, 4 jumpers, 4 pajama sets (top and bottom), and 20 t-shirts, then asks his friends if they have anything they want to donate. 3 of his friends donate the same amount of clothing as Adam each. Then he takes another look over his clothing and decides that he actually wants to keep half of his clothes. How many articles of clothing are being donated in total? As pajama sets are made up of a top and a bottom, there are 4 pajama sets * 2 = <<4*2=8>>8 articles of clothing from Adam's donation. In total, Adam is donating 4 pairs of pants + 4 jumpers + 8 pajama pieces + 20 t-shirts = <<4+4+8+20=36>>36 articles of clothing. Together, the 3 friends donate a total of 36 articles of clothing per friend * 3 friends = <<36*3=108>>108 articles of clothing. Adam changes his mind and takes back half, which means he is now actually donating 36 / 2 = <<36/2=18>>18 articles of clothing. There is therefore now a total of 108 + 18 = <<108+18=126>>126 articles of clothing being donated. #### 126 Wade is the star player of the basketball team. His average points per game is 20, and his teammates' average points per game is 40. How many points will their team have in total after 5 games? Wade's points is 5 x 20 = <<5*20=100>>100 after 5 games. His teammates' points is 40 x 5 = <<40*5=200>>200 after 5 games. So, the total score of the whole team is 100 + 200 = <<100+200=300>>300 after five games." #### 300 Karl sells clothing in his store. He sells a T-shirt that costs $5, some pants that cost $4, and some skirts that cost $6, he also sells some refurbished t-shirts that cost half the original price. How much is his total income if he sold two T-shirts, one pair of pants, four skirts, and six refurbished T-shirts? The refurbished T-shirt costs $5 / 2 = $<<5/2=2.5>>2.5. He earn $2.5 x 6 = $<<2.5*6=15>>15 for the refurbished T-shirt. He can earn $5 x 2 = $<<5*2=10>>10 for the T-shirts. He can earn $4 x 1 = $<<4*1=4>>4 for the pants. He can earn $6 x 4 = $<<6*4=24>>24 for the skirts. Therefore Karl can earn a total of $15 + $10 + $4 + $24 = $<<15+10+4+24=53>>53. #### 53 A box of chocolate bars was shared equally between Mike, Rita and Anita. If the box contains 12 bars, how many bars did Mike and Rita get (combined)? A box of 12 bars was shared equally between 3 people so each person got 12/3 = <<12/3=4>>4 bars Mike and Rita together got 4+4 = <<4+4=8>>8 bars #### 8 At the polar bear club, Jerry and his three friends, Elaine, George, and Kramer, took turns jumping into a swimming pool filled with freezing-cold water. Jerry was in the pool for 3 minutes before becoming too cold to remain in the cold water. Elaine stayed in the pool for twice as long as Jerry. George could only stay in the pool for one-third as long as Elaine. And Kramer, who accidentally locked himself in the bathroom, could not find the pool. What is the combined total of minutes that Jerry and his friends were in the cold water? Elaine was in the pool for 2*3=<<2*3=6>>6 minutes. George was in the pool for 6/3=<<6/3=2>>2 minutes. Kramer never found the pool and thus swam for 0 minutes. In total, Jerry and his friend were in the cold water for 3+6+2+0=<<3+6+2+0=11>>11 minutes. #### 11 Steve has decided to become a baker. On Mondays, Wednesdays and Fridays, he bakes apple pies. On Tuesdays and Thursdays, he bakes cherry pies. If he bakes 12 pies per day, how many more apple pies does he bake than cherry pies in one week? In one week, he bakes 3 * 12 = <<3*12=36>>36 apple pies. In one week, he bakes 2 * 12 = <<2*12=24>>24 cherry pies. He bakes 36 - 24 = <<36-24=12>>12 more apple pies. #### 12 The class plans to take a field trip to the zoo. The cost to rent a school bus is $100. The cost of admission is $10 per student. The teacher is allowed in for free. If the class has a budget of $350, how many students can go on the field trip? There is $350 - $100 = $<<350-100=250>>250 available to pay for the students' admission fees. This means they can afford to bring $250 / $10 = <<250/10=25>>25 students on the trip. #### 25
