Jon's laundry machine can do 5 pounds of laundry at a time. 4 shirts weigh 1 pound and 2 pairs of pants weigh 1 pound. If he needs to wash 20 shirts and 20 pants, how many loads of laundry does he have to do?

The shirts weigh 20/4=

<<20/4=5>>5 pounds The pants weigh 20/2=<<20/2=10>>10 pounds So he needs to do 10+5=<<10+5=15>>15 pounds of laundry So that would take 15/5=<<15/5=3>>3 loads of laundry #### 3 Thomas is training at the gym to prepare for a competition. He trained for 5 hours every day for a month (30 days). If he continues to train for the next 12 days, how many hours will he spend on training in total? In total Thomas would train on 30 + 12 = <<30+12=42>>42 days. Thomas trained 5 hours every day, which would bring us to 42 * 5 = <<42*5=210>>210 hours of training in total. #### 210 Amber is baking cakes for her party. She has invited 8 friends and each one will want two slices of cake. Each cake makes 6 slices. If she bakes 4 cakes, how many slices will be left over at the end if she eats three herself? Her friends will eat 16 slices of cake because 8 x 2 = <<8*2=16>>16 There will be 19 slices eaten in total because 16 + 3 = <<16+3=19>>19 She is making 24 slices of cake because 4 x 6 = <<4*6=24>>24 There will be 5 pieces left over because 24 - 19 = <<24-19=5>>5 #### 5 John is lifting weights. He bench presses 15 pounds for 10 reps and does 3 sets. How much total weight does he move? He presses 15 pounds x 10 reps = <<15*10=150>>150 pounds He moves 3 sets x 150 pounds = <<3*150=450>>450 pounds in total. #### 450 Travis is hired to take 638 bowls from the factory to the home goods store. The home goods store will pay the moving company a $100 fee, plus $3 for every bowl that is delivered safely. Travis must pay the home goods store $4 each for any bowls that are lost or broken. If 12 bowls are lost, 15 bowls are broken, and the rest are delivered safely, how much should Travis be paid? Travis has lost or broken 12 + 15 = <<12+15=27>>27 bowls. Travis will need to pay the store 27 x $4 = $<<27*4=108>>108 dollars. Travis has safely taken 638 - 27 = <<638-27=611>>611 bowls. For this, he will be paid 611 x $3 = $<<611*3=1833>>1833 dollars In total Travis will be paid $1833 + $100 = $<<1833+100=1933>>1933 dollars. Since Travis has to pay the home goods 108 for the broken and lost bowls, he will end up with $1933-$108 = $1825. #### 1825 Sam has 19 dimes and 6 quarters. She buys 4 candy bars for 3 dimes each and 1 lollipop for 1 quarter. How much money, in cents, does she have left? The candy bars cost 4*3=<<4*3=12>>12 dimes. Sam has 19-12=<<19-12=7>>7 dimes left. Sam has 6-1=<<6-1=5>>5 quarters left. Sam has 7*10+5*25=<<7*10+5*25=195>>195 cents left. #### 195 Gary is buying chlorine for his rectangular pool, which is 10 feet long, 8 feet wide, and 6 feet deep. Gary needs to buy one quart of chlorine for every 120 cubic feet of water in his pool. If chlorine costs $3 a quart, how much does Gary spend on chlorine? First find the volume of the pool by multiplying the length by the width by the height: 10 ft * 8 ft * 6 ft = <<10*8*6=480>>480 cubic feet Then divide the volume of the pool by the number of cubic feet one quart of chlorine can sterilize: 480 cubic feet / 120 cubic feet/quart = <<480/120=4>>4 quarts Then multiply the number of quarts Gary needs to buy by the price per quart to find out how much money he spends: $3/quart * 4 quarts = $<<3*4=12>>12 #### 12 Mandy is 3 years old. Her brother is 4 times as old as she is. Her sister is 5 years younger than her brother. What is the age difference between Mandy and her sister? Mandy's brother's age is 3 years x 4 = <<3*4=12>>12 years old. Her sister's age is 12 years - 5 years = <<12-5=7>>7 years old. The age difference between Mandy and her sister is 7 years - 3 years = <<7-3=4>>4 years. #### 4 Kara has to drink 4 ounces of water every time she takes her medication. Her medication instructions are to take one tablet three times a day. She followed the instructions for one week, but in the second week, she forgot twice on one day. How many ounces of water did she drink with her medication over those two weeks? Kara drinks 4 * 3 = <<4*3=12>>12 ounces of water with her medication each day. In a week, she drinks 12 * 7 = <<12*7=84>>84 ounces of water with her medication. In two weeks, she drinks 84 * 2 = <<84*2=168>>168 ounces of water with her medication. One day, she forgot two tablets, so she did not drink 2 * 4 = <<2*4=8>>8 ounces of water. Thus, Kara drank 168 - 8 = <<168-8=160>>160 ounces of water with her medication over two weeks. #### 160 Janelle had 26 green marbles. Then she bought 6 bags of blue marbles. There were 10 marbles in each bag. She created a gift of 6 green marbles and 8 blue marbles and gave it to a friend. How many marbles does Janelle have now? Janelle has 6 bags * 10 blue marbles = <<6*10=60>>60 marbles. Janelle has a total of 26 green marbles + 60 blue marbles = <<26+60=86>>86 marbles. Janelle gave away a gift of 6 green + 8 blue marbles = <<6+8=14>>14 marbles. Janelle has a final amount of 86 marbles - 14 marbles = <<86-14=72>>72 marbles. #### 72
