Jess made 3 different stacks of wooden blocks. The first stack was 7 blocks high, the second stack was 5 block(s) higher than the first, and the final stack was 7 block(s) higher than the second. Jess’ little sister knocked over the entire first tower, in the second tower she left 2 blocks standing, and in the final tower she left 3 blocks standing. How many blocks in total fell down?

Jess’ second stack was 7 blocks + 5 blocks =

<<7+5=12>>12 blocks. Jess’ third stack was 12 blocks + 7 blocks = <<12+7=19>>19 blocks high. Jess’ sister knocked down the second tower and knocked 12 blocks – 2 = <<12-2=10>>10 blocks knocked over. Jess’ sister knocked down the final tower and knocked 19 blocks – 3 = <<19-3=16>>16 blocks knocked over. Total blocks knocked over was 7 blocks + 10 + 16 = <<7+10+16=33>>33 blocks. #### 33 Every week, Lucas makes 4 pieces of chocolate candy for each of his students on Monday. He made 40 pieces of chocolate candy last Monday. This upcoming Monday, 3 of Lucas' students will not be coming to class. How many pieces of chocolate candy will Lucas make for his class on Monday? Since Lucas makes 4 pieces of chocolate per student, he has 40 / 4 = <<40/4=10>>10 students. This upcoming Monday, there will be 10 - 3 = <<10-3=7>>7 students. Lucas will make 4 * 7 = <<4*7=28>>28 pieces of chocolate candy. #### 28 John assembles computers and sells prebuilt computers as a business. The parts for the computer cost $800. He sells the computers for 1.4 times the value of the components. He manages to build 60 computers a month. He has to pay $5000 a month in rent and another $3000 in non-rent extra expenses a month. How much profit does he make a month? He sells each computer for 1.4*800=$<<1.4*800=1120>>1120 That means he makes a profit of 1120-800=$<<1120-800=320>>320 per computer So he makes 320*60=$<<320*60=19200>>19200 from selling computers He has extra expenses of 5000+3000=$<<5000+3000=8000>>8000 a month So his profit is 19200-8000=$<<19200-8000=11200>>11,200 #### 11200 Robbie weighs 100 pounds. Patty was 4.5 times as heavy as Robbie, but she has since lost 235 pounds by working out. How many more pounds does Patty weigh than Robbie now? Patty used to weigh 100*4.5 = <<100*4.5=450>>450 pounds. Patty weighs 450-235 = <<450-235=215>>215 pounds after working out. Patty weighs 215-100 = <<215-100=115>>115 more pounds than Robbie. #### 115 Jason is tired of the neighborhood animals raiding his trash. He pepper-sprays some raccoons and 6 times as many squirrels. If he pepper-sprays 84 animals total, how many raccoons does he pepper-spray? Let r be the number of raccoons Jason pepper-sprays and s be the number of squirrels. We know that r + s = 84 and s = 6r. Substituting the second equation into the first equation, we get r + 6r = 84 Combining like terms, we get 7r = 84 Dividing both sides by 7, we get r = 12 #### 12 A chef has served 58 adults, 35 fewer children than the number of adults, and twice as many seniors as children. What is the total number of guests served? The chef has served 58 - 35 = <<58-35=23>>23 children. The chef has served 23 x 2 = <<23*2=46>>46 seniors. Therefore, the total number of guests that the chef has served is 58 + 23 + 46 = <<58+23+46=127>>127. #### 127 Carrie is making punch. She adds 6 12-oz cans of Mountain Dew, 28 oz of ice, and a 40 oz bottle of fruit juice. How many 10 oz servings of punch does Carrie have? First find the total volume of the Mountain Dew: 6 cans * 12 oz/can = <<6*12=72>>72 oz Then find the total volume of the punch: 72 oz + 28 oz + 40 oz = <<72+28+40=140>>140 oz Then divide the total volume by the volume of each serving to find the number of servings: 140 oz / 10 oz/serving = <<140/10=14>>14 servings #### 14 Nathan plays amateur baseball. He played for 3 hours for two weeks, every day. His friend Tobias played for 5 hours every day, but only for one week. How many hours did Nathan and Tobias play in total? Two weeks are 14 days, so Nathan played for 3 * 14 = <<14*3=42>>42 hours. Tobias played for 7 days, so he played a total of 5 * 7 = <<5*7=35>>35 hours. Nathan and Tobias played together for 42 + 35 = <<42+35=77>>77 hours. #### 77 A piece of wire 5 feet 4 inches long was divided into 4 equal parts. How long was each part in inches if 1 foot is equal to 12 inches? Five feet is equal to 5 feet x 12 inches/foot = <<5*12=60>>60 inches. So, the total length of the wire was 60 inches + 4 inches = <<60+4=64>>64 inches. Hence, each part is 64 inches / 4 parts = <<64/4=16>>16 inches/part. #### 16 Rob has 24 baseball cards, and a few are doubles. One third of Rob's cards are doubles, and Jess has 5 times as many doubles as Rob. How many doubles baseball cards does Jess have? Rob has 24/3=<<24/3=8>>8 doubles baseball cards. Jess has 8*5=<<8*5=40>>40 doubles baseball cards. #### 40
