James can do a farmer's walk with 300 pounds per hand for 20 meters. He can lift 30% more if he only goes 10 meters. In addition, lifting straps give him another 20%. How much can he move with lifting straps for 10 meters if he increases his 20-meter distance without straps by 50 pounds and everything else increases in proportion?

After the increase, he can lift 300+50=

<<300+50=350>>350 pounds Decreasing the distance increase the amount he can lift by 350*.3=<<350*.3=105>>105 pounds So he can lift 350+105=<<350+105=455>>455 for 10 feet The straps add another 455*.2=<<455*.2=91>>91 pounds So his total weight is 455+91=<<455+91=546>>546 pounds per hand #### 546 Mr. Gardner bakes 20 cookies, 25 cupcakes, and 35 brownies for his second-grade class of 20 students. If he wants to give each student an equal amount of sweet treats, how many sweet treats will each student receive? Mr. Gardner bakes a total of 20 + 25 + 35 = <<20+25+35=80>>80 sweet treats Each student will receive 80 / 20 = <<80/20=4>>4 sweet treats #### 4 A mother planted a 16-inch tree on her son's first birthday. On the day the tree was planted, the boy was 24 inches tall. If the tree grows twice as fast as the boy does, how tall will the tree be by the time the boy is 36 inches tall? The boy grew 36 - 24 = <<36-24=12>>12 inches since the tree was planted. Since the tree grows twice as fast as the boy, it will have grown 12*2 = <<12*2=24>>24 inches during this time period. Thus, the final height of the tree is 16 + 24 = <<16+24=40>>40 inches. #### 40 Melisa and Jennifer threw a fiftieth birthday party for their father at a local restaurant. When the bill came, Melisa added a 15% tip of $42. Jennifer said that the service was wonderful and they should leave a 20% tip instead. How much is a 20% tip? If 15% is known to be $42, then 5% can be found by dividing $42 ÷ 3 = $<<42/3=14>>14. So 20% is $14 + $42 = $56. #### 56 Sean buys 3 cans of soda, 2 soups, and 1 sandwich. Each soup cost as much as the 3 combined sodas. The sandwich cost 3 times as much as the soup. If the soda cost $1 how much did everything cost together? The soda cost 3*1=$<<3*1=3>>3 So the soups cost 2*3=$<<2*3=6>>6 The sandwich cost 3*3=$<<3*3=9>>9 So the total cost of everything was 3+6+9=$<<3+6+9=18>>18 #### 18 3 years ago James turned 27. In 5 years Matt will be twice James age. How old is Matt now? James is now 27+3=<<27+3=30>>30 years old In 5 years James will be 30+5=<<30+5=35>>35 years old So in 5 years Matt will be 35*2=<<35*2=70>>70 years old That means Matt is now 70-5=<<70-5=65>>65 years old #### 65 Madison and Gigi have to run a total of 2400 meters in gym class. The track is 150 meters around. If they each have run 6 laps, how many more laps do they have to run before they reach 2400 meters? The have run 12 laps because 6 + 6 = <<6+6=12>>12 They have run 1,800 meters because 12 x 150 = <<12*150=1800>>1,800 They have 600 more meters to run because 2,400 - 1,800 = <<2400-1800=600>>600 The have to run 4 more laps because 600 / 150 = <<600/150=4>>4 #### 4 Stephen made 10 round trips up and down a 40,000 foot tall mountain. If he reached 3/4 of the mountain's height on each of his trips, calculate the total distance he covered. Up a mountain, Stephen covered 3/4*40000 = <<3/4*40000=30000>>30000 feet. Coming down, Stephen covered another 30000 feet, making the total distance covered in one round to be 30000+30000 = <<30000+30000=60000>>60000. Since Stephen made 10 round trips up and down the mountain, he covered 10*60000 = <<10*60000=600000>>600000 #### 600000 Katy makes some brownies to eat throughout the week. She eats 5 on Monday and twice as many on Tuesday. After she has eaten the brownies on Tuesday, all of the brownies she made are gone. How many brownies did Katy make? On Tuesday, Katy ate 5 brownies * 2 = <<5*2=10>>10 brownies. As she has eaten all of the brownies she made, she must have made 5 Monday brownies + 10 Tuesday brownies = <<5+10=15>>15 brownies. #### 15 Mark buys a Magic card for $100, which then triples in value. How much profit would he make selling it? The value went up to 100*3=$<<100*3=300>>300 So he gained 300-100=$<<300-100=200>>200 #### 200
