Jerry’s two daughters play softball on different teams. They each have 8 games this season. Each team practices 4 hours for every game they play. If each game lasts for 2 hours, how many hours will Jerry spend at the field watching his daughters play and practice altogether?
Jerry will spend 8 games x 2 hours per game =
<<8*2=16>>16 hours watching one daughter play her games. He will spend 16 x 2 = <<16*2=32>>32 hours watching both daughters play their games. He will spend 8 games x 4 hours of practice = <<8*4=32>>32 hours watching one daughter practice. He will spend 32 x 2 = <<32*2=64>>64 hours watching both daughters practice. He will spend a total of 32 hours watching games + 64 hours watching practice = <<32+64=96>>96 hours. #### 96 A bear is preparing to hibernate for the winter and needs to gain 1000 pounds. At the end of summer, the bear feasts on berries and small woodland animals. During autumn, it devours acorns and salmon. It gained a fifth of the weight it needed from berries during summer, and during autumn, it gained twice that amount from acorns. Salmon made up half of the remaining weight it had needed to gain. How many pounds did it gain eating small animals? The bear gained 1 / 5 * 1000 = <<1/5*1000=200>>200 pounds from berries. It gained 2 * 200 = <<2*200=400>>400 pounds from acorns. It still needed 1000 - 200 - 400 = <<1000-200-400=400>>400 pounds. Thus, it gained 400 / 2 = <<400/2=200>>200 pounds from salmon. Therefore, the bear gained 400 - 200 = <<400-200=200>>200 pounds from small animals. #### 200 There are 290 liters of oil in 24 cans. If 10 of the cans are holding 8 liters each, how much oil is each of the remaining cans holding? 10 cans are holding 8 liters each for a total of 10 * 8 = <<10*8=80>>80 liters There are 290 - 80 = <<290-80=210>>210 litres left There are 24 - 10 =<<24-10=14>>14 cans left Each of the remaining cans is holding 210 / 14 = <<210/14=15>>15 liters each #### 15 Shawna's workout goal is 30 situps. On Monday, Shawna was only able to do 12 situps, so she decided that she would make up for the rest on Tuesday. However, she was only able to do 19 situps on Tuesday. How many situps would Shawna have to do on Wednesday to meet her minimum goal and make up for the ones she didn't do? On Monday, Shawna was short of 30 - 12 = <<30-12=18>>18 situps On Tuesday, Shawna was short of 30 - 19 = <<30-19=11>>11 situps On Wednesday, Shawna would have to do 30 + 18 + 11 = <<30+18+11=59>>59 situps #### 59 James earns $20 an hour while working at his main job. He earns 20% less while working his second job. He works 30 hours at his main job and half that much at his second job. How much does he earn per week? James earns 20*.2=$<<20*.2=4>>4 less while working his second job So he earns 20-4=$<<20-4=16>>16 an hour At his first job he earns 20*30=$<<20*30=600>>600 He works 30/2=<<30/2=15>>15 hours at his second job So he earns 15*16=$<<15*16=240>>240 So he earns 600+240=$<<600+240=840>>840 a week #### 840 Lee mows one lawn and charges $33. Last week he mowed 16 lawns and three customers each gave him a $10 tip. How many dollars did Lee earn mowing lawns last week? 33 * 16 = $<<33*16=528>>528 3 * 10 = $<<3*10=30>>30 528 + 30 = $<<528+30=558>>558 Lee earned $558 mowing lawns last week. #### 558 Tara has been planning to buy a laptop which costs $1000. A computer shop accepts payment in installments of $65 per month provided that a 20% down payment is made. If Tara wants to pay an additional $20 for the down payment, how much will her balance be after paying for 4 months? Tara has to make a $1000 x 20/100 = $<<1000*20/100=200>>200 down payment. Since Tara wants to pay $20 more for the down payment, her total down payment will be $200 + $20 = $<<200+20=220>>220. So her remaining balance payable over a year is $1000 - $220 = $<<1000-220=780>>780. Tara has to make a monthly payment of $780/year / 12 months/year = $<<780/12=65>>65/month. The total cost of her payments for 4 months is $65/month x 4 months = $<<65*4=260>>260. Therefore, Tara's balance after 4 months is $780 - $260 = $<<780-260=520>>520. #### 520 Jesse and Mia are competing in a week long race. They have one week to run 30 miles. On the first three days Jesse averages (2/3) of a mile. On day four she runs 10 miles. Mia averages 3 miles a day over the first 4 days. What is the average of their average that they have to run over the final three days? Jesse runs 2 miles in the first three days because 3 x (2/3) = <<3*(2/3)=2>>2 Jesse has 18 miles left to run because 30 - 10 - 2 = <<30-10-2=18>>18 Jesse has to run an average of 6 miles a day because 18 / 3 = <<18/3=6>>6 Mia runs 12 miles over the first four days because 4 x 3 = <<4*3=12>>12 She has 18 miles left to run because 30 - 12 = <<30-12=18>>18 She has to run six miles a day because 18 / 3 = <<18/3=6>>6 The total they both have to run is <<12=12>>12 miles a day The average they have to run per day on average is 6 miles because 12 / 2 = <<12/2=6>>6 #### 6 The ratio of coins that Elsa has to that which Amalie has is 10:45. If the total number of coins they have is 440, and Amalie spends 3/4 of what she has on toys, how many will she remain with? The total ratio of the coins they both have is 10+45 = <<10+45=55>>55 The fraction of the ratio representing the number of coins that Amalie has is 45/55, and since the total number of coins they both have is 440, Amalie has 45/55*440 = <<45/55*440=360>>360 coins. When Amalie spends 3/4 of what she has, she parts with 3/4*360 = <<3/4*360=270>>270 coins. She still has 360 coins - 270 coins = <<360-270=90>>90 coins #### 90 Carly collected 7 starfish with 5 arms each and one seastar with 14 arms. How many arms do the animals she collected have in total? First find the total number of starfish arms: 7 starfish * 5 arms/starfish = <<7*5=35>>35 arms Then add the number of seastar arms to find the total number of arms: 35 arms + 14 arms = <<35+14=49>>49 arms #### 49
