John weighs one-quarter times more than what Mary weighs. Mary weighs 20 lbs less than Jamison's weight. If Mary weighs 160 lbs, what's the combined weight of the three?

If Mary weighs 160 lbs, Jamison weighs 160 lbs + 20 lbs =

<<160+20=180>>180 lbs. If John weighs one-quarter less than what Mary weighs, he weighs 1/4 * 160 lbs = <<1/4*160=40>>40 lbs more. The total weight of John is 160 lbs + 40 lbs = <<160+40=200>>200 lbs. The total weight for the three is 200 lbs + 180 lbs + 160 lbs = <<200+180+160=540>>540 lbs. #### 540 There are 100 jellybeans in a glass jar. Mrs. Copper’s kindergarten class normally has 24 kids, but 2 children called in sick and stayed home that day. The remaining children who attended school eat 3 jellybeans each. How many jellybeans are still left in the jar? With the sick children who stayed home, there are this many kindergarten students in the class: 24 - 2 = <<24-2=22>>22 kids. This many jellybeans are eaten: 22 x 3 = <<22*3=66>>66 jellybeans. This many jellybeans are still left in the jar: 100 - 66 = <<100-66=34>>34 jellybeans. #### 34 Bill gets a flat-screen TV that measures 48 inches by 100 inches. His brother Bob gets a TV that measures 70 inches by 60 inches. If the TVs weigh 4 oz per square inch of screen space, how much more does the heavier TV weigh in pounds? (There are 16 ounces per pound). First find the screen area of Bill's TV: 48 inches * 100 inches = <<48*100=4800>>4800 square inches Then find the screen area of Bob's TV: 70 inches * 60 inches = <<70*60=4200>>4200 square inches Then subtract the size of the smaller TV from the size of the bigger TV to find the size difference: 4800 square inches - 4200 square inches = <<4800-4200=600>>600 square inches Then multiply the size difference by the weight per square inch to find the weight difference: 600 square inches * 4 oz/square inch = <<600*4=2400>>2400 oz Then divide the weight difference in ounces by the number of ounces per pound to find the weight difference in pounds: 2400 oz / 16 oz/pound = <<2400/16=150>>150 pounds #### 150 Dave bought 8 books about animals, 6 books about outer space, and 3 books about trains to keep him busy over the holidays. Each book cost $6. How much did Dave spend on the books? Dave buys 8 books + 6 books + 3 books = <<8+6+3=17>>17 books in total. He has to spend 17 books × $6/book = $<<17*6=102>>102 if he wants to buy all the books. #### 102 To increase her water intake to the recommended level by her doctor, Happy has to take 40% more cups of water than she takes now. If she is currently drinking 15 cups of water every week, what's the recommended number of cups per week? Happy has to take 40/100 * 15 = <<40/100*15=6>>6 more cups of water than she takes currently to reach the recommended water intake levels by her doctor. In total, she is supposed to drink 6+15 = <<6+15=21>>21 cups of water every week. #### 21 Javier spends 30 minutes outlining his speech, 28 more minutes writing than outlining, and half as much time practicing as writing. How much time does he spend on his speech in total? First find the total time Javier spends writing: 30 minutes + 28 minutes = <<30+28=58>>58 minutes Then divide that amount of time by 2 to find how much time he spends practicing: 58 minutes / 2 = <<58/2=29>>29 minutes Then add the time he spends outlining, writing and practicing to find his total time spent: 29 minutes + 58 minutes + 30 minutes = <<29+58+30=117>>117 minutes #### 117 A swarm of ants discovered a pile of sugar that spilled from a dropped bag. They begin to harvest it and carry it off to their anthill. Every hour, the ants remove 4 ounces of sugar. The bag of sugar held 24 ounces before it was dropped. After three hours, how many more hours will the ants need to harvest the remaining sugar? After 3 hours, the ants have removed 4 * 3 = <<4*3=12>>12 ounces of sugar. There are 24 - 12 = <<24-12=12>>12 ounces of sugar left. Thus, the ants need 12 / 4 = <<12/4=3>>3 more hours to harvest the remaining sugar. #### 3 Katerina purchases 3 pots and 4 pans at the home goods store. Each pot costs $20. The total cost of Katerina's items is $100. If each pan is the same price, what is the cost of 2 pans? The cost of the pots is 3 * $20 = $<<3*20=60>>60 The cost of 4 pans is $100 - $60 = $40 Since each pan is the same price, the cost of 1 pan is $40 / 4 = $<<40/4=10>>10 The cost of 2 pans is $10 + $10 = $<<10+10=20>>20 #### 20 John decides to get the vaccine for COVID. He has to wait 20 minutes for the first dose. The second dose has a wait time half as long. How long was the total wait time? The second dose had a wait time of 20/2=<<20/2=10>>10 minutes So the total wait time is 20+10=<<20+10=30>>30 minutes #### 30 Corey downloaded two movie series from his Netflix account with 12 and 14 seasons per series, respectively. However, in the week, his computer got a mechanical failure, and he lost two episodes from each season for both series. If each season in the movie series that Corey downloaded had 16 episodes, how many episodes remained after the computer's mechanical failure? In the first movie series with 12 seasons, after the mechanical failure, the number of episodes that Corey lost is 2*12 = <<2*12=24>>24 Originally, the movie series with 12 seasons had 12*16 = <<12*16=192>>192 episodes. After the mechanical failure, Corey had 192-24 = <<192-24=168>>168 episodes remaining in the first movie series. Similarly, the 14 season movie series also had 14*2 = <<14*2=28>>28 lost after the computer's mechanical failure. Originally, the movie series with 14 seasons has 14*16 = <<14*16=224>>224 episodes. The mechanical failure of the computer reduced the number of episodes in the 14 season movie series to 224-28 = <<224-28=196>>196 After the loss, Corey had 196+168 = <<196+168=364>>364 episodes remaining from the two movie series he had downloaded. #### 364
