Martin went to a store to buy a new television set. He decided to spend no more than $1,000 and the sales clerk offered him the TV for $100 less and an additional 20% off. How much lower was the price of the television than the amount Martin decided to spend?

The seller has offered him the TV for 1000 - 100 = $

<<1000-100=900>>900. The discount on the television was 900 * 20/100 = $<<900*20/100=180>>180. The final price of the television is therefore 900 - 180 = $<<900-180=720>>720. Martin was able to save 1000 - 720 = $<<1000-720=280>>280. #### 280 Steve has 25 socks. He has 4 pairs of socks that match, and all the others don't match. How many mismatching socks does Steve have altogether? In each pair of socks there are 2/1 = <<2/1=2>>2 socks. Steve has 2*4 = <<2*4=8>>8 matching socks. Steve has 25-8 = <<25-8=17>>17 mismatching socks. #### 17 At Kaleb's Restaurant, a group with six adults and two children came in to eat. If each adult meal cost six dollars and each children's meal was $4, and every person ordered a soda for $2 how much was the bill? The cost for adult meals is 6 adults * $6 = $<<6*6=36>>36. The cost for children's meals is 2 children * $4 = $<<2*4=8>>8. The total people ordering drinks is 6 + 2 = <<6+2=8>>8. The cost for drinks is 8 people * $2 = $<<8*2=16>>16. The total cost for the meal is $36 + $8 + $16 = $<<36+8+16=60>>60. #### 60 Mrs. Jackson has four boxes of Christmas decorations. There are 15 decorations in each box. She was only able to use 35 decorations and decided to give the rest to her neighbor. How many decorations did she give? Mrs. Jackson had a total of 4 x 15 = <<4*15=60>>60 decorations. Then she gave 60 - 35 = <<60-35=25>>25 decorations to her neighbor. #### 25 Philip has a farm with animals. He has 20 cows, 50% more ducks. Philip also has as many pigs as one-fifth of ducks and cows in total. How many animals does Philip have on his farm? Philip has 50/100 * 20 = <<50/100*20=10>>10 more ducks than cows. Which means he has 20 + 10 = <<20+10=30>>30 ducks. So Philip's cows and ducks sum up to 20 + 30 = <<20+30=50>>50 animals. If there are 50 cows and ducks, that means Philip has 1/5 * 50 = <<50*1/5=10>>10 pigs. In total Philip has 50 + 10 = <<50+10=60>>60 animals on his farm. #### 60 To make a lasagna Martha needs 1.5kg of cheese and 500 grams of meat. The cheese costs $6 per kilogram, and the meat $8 per kilogram. How much does Martha need to pay for the ingredients? 500 grams is 0.5 kilogram, so for the meat, Martha needs to pay 0.5 * 8 = $4. For the cheese, Martha needs to pay 1.5 * 6 = $<<1.5*6=9>>9. So in total for the ingredients, Martha needs to pay 4 + 9 = $<<4+9=13>>13. #### 13 A hand-crank pencil sharpener can sharpen one pencil every forty-five seconds. An electric version can sharpen one in twenty seconds. How many more pencils can the electric sharpener sharpen than the hand-crank sharpener in six minutes? A minute is 60 seconds, so 6 minutes is 6 * 60 = <<6*60=360>>360 seconds. A hand-crank sharpener can sharpen 360 / 45 = <<360/45=8>>8 pencils in 6 minutes. An electric sharpener can sharpen 360 / 20 = <<360/20=18>>18 pencils in 6 minutes. Therefore, an electric sharpener can sharpen 18 - 8 = <<18-8=10>>10 more pencils than a hand-crank in 6 minutes. #### 10 The Tampa Bay Bucs have 13 football players and 16 cheerleaders. If 10 football players and 4 cheerleaders quit, how many football players and cheerleaders are left? There are 13 - 10 = <<13-10=3>>3 football players left. There are 16 - 4 = <<16-4=12>>12 cheerleaders left. In total there are 3 + 12 = <<3+12=15>>15 football players and cheerleaders left. #### 15 Twenty people pre-bought plane tickets at a price of $155 per ticket. Thirty people bought their plane tickets at the gate and they each paid $200 for their ticket. How many more dollars did the people at the gate pay for their tickets than those passengers that pre-bought their tickets? Pre-bought: 20 people * $155 = $<<20*155=3100>>3100 Gate bought: 30 people * $200 = $<<30*200=6000>>6000 $6000 - $3100 = $<<6000-3100=2900>>2900 The passengers that paid at the gate paid $2900 more dollars than those who pre-bought their tickets. #### 2900 Radhika got a new gaming system and asked everyone to get her games as gifts to add to the games she already has that she bought with her gaming system. On Christmas, she is given 12 new video games. On her birthday in February, she is given 8 more video games. Radhika already owned 1/2 the number of games as what she was given on Christmas and her birthday. How many video games does she own now? Radhika was given 12 video games on Christmas and 8 video games on her birthday, so she was given 12 + 8 = <<12+8=20>>20 video games. She had 1/2 this many before she was given gifts, 20 / 2 = <<20/2=10>>10 video games she already owned. She was given 20 video games and had 10 already, 20 + 10 = <<20+10=30>>30 video games. Now Radhika has 30 video games. #### 30
