Holly loves to drink chocolate milk. With breakfast, she drinks 8 ounces of chocolate milk before leaving for work. During her lunch break, she buys a new 64-ounce container of chocolate milk and then drinks 8 ounces of it. With dinner, she drinks another 8 ounces of chocolate milk. If she ends the day with 56 ounces of chocolate milk, how many ounces of chocolate milk did she begin the day with?
Before dinner, she had 56+8=
<<56+8=64>>64 ounces of CM. Before drinking 8 ounces of CM during lunch, she had 64+8=<<64+8=72>>72 ounces of CM. Before buying 64 ounces of CM, she had 72-64=<<72-64=8>>8 ounces of CM. And before breakfast, she had 8+8=<<8+8=16>>16 ounces of chocolate milk. #### 16 Mary is building a mosaic for her school cafeteria's wall. It will be 10 feet tall and 15 feet long. Each tile she uses is 1 inch square. How many tiles will she need? First convert the length of the mural to inches: 15 feet * 12 inches/foot = <<15*12=180>>180 inches Then convert the height of the mural to inches: 10 feet * 12 inches/foot = <<10*12=120>>120 inches Then multiply the length and the height to find the total area of the mural: 180 inches * 120 inches = <<180*120=21600>>21600 square inches. Since each tile is 1 square inch, this is also the number of tiles she needs. #### 21600 Barbara got a great deal on a new chest of drawers, but she has to take a lot of paper out of the drawers to be able to use it. She found 3 bundles of colored paper, 2 bunches of white paper, and 5 heaps of scrap paper. If a bunch holds 4 sheets of paper, a bundle holds 2 sheets of paper, and a heap holds 20 sheets of paper, how many sheets of paper did Barbara remove from the chest of drawers? Of the colored paper, Barbara removed 3 * 2 = <<3*2=6>>6 sheets of paper. Of the white paper, she removed 2 * 4 = <<2*4=8>>8 sheets of paper. Of the scrap paper, she removed 5 * 20 = <<5*20=100>>100 sheets of paper. So in total, Barbara removed 6 + 8 + 100 = <<6+8+100=114>>114 sheets of paper. #### 114 Oliver is working out in a gym. On Monday he worked out for 4 hours, and the next day for 2 hours less. On Wednesday he decided to work out twice as much as on Monday. On Thursday the gym was closed, so Oliver needed to exercise at home which took twice as much time as on Tuesday. How many hours in total have Oliver worked out during these four days? On Tuesday, Oliver worked out for 4 - 2 = <<4-2=2>>2 hours. On Wednesday he decided to work out twice as much as on Monday, so for 2 * 4 = <<2*4=8>>8 hours. On Thursday, at home, Oliver trained twice as much as on Tuesday, so for 2 * 2 = <<2*2=4>>4 hours. In total Oliver trained for 4 + 2 + 8 + 4 = <<4+2+8+4=18>>18 hours. #### 18 Two brick walls are being built. Each wall has 30 bricks in a single row and there are 50 rows in each wall. How many bricks will be used to make both walls? Each brick wall needs 30 x 50 = <<30*50=1500>>1500 bricks. Thus, the two walls need 1500 x 2 = <<1500*2=3000>>3000 bricks. #### 3000 After shearing her 200 sheep, Azalea paid the shearer who had come to help her with the work $2000 for his job. Each of the sheared sheep produced 10 pounds of wool. If Ms. Azalea sold a pound of wool at $20, how much profit did she make from the produce of her sheep farm? Since there were 200 sheep, the amount of wool Azalea got after the shearing of the sheep is 200*10 = <<200*10=2000>>2000 pounds of wool. If she sold one pound of wool at $20, the total amount of money she made from the sheep farm is 2000*$20 = $<<2000*20=40000>>40000 Her profit, which is $2000 less the amount of money she paid to the shearer, is $40000-$2000 = 38000 #### 38000 When Pogo, the four-legged martian, walks across the soft Martian soil, it leaves 4 footprints every meter. But Grimzi, the three-legged Plutonian, leaves only 3 footprints in the soft sands of Pluto for every 6 meters it walks. If Pogo travels 6000 meters across the soil of Mars, and Grimzi travels for 6000 meters across the fine sands of Pluto, what is the combined total number of footprints the two creatures will leave on the surfaces of their respective planets? Since Pogo leaves 4 prints per meter, then over 6000 meters it would leave 4*6000=<<4*6000=24000>>24,000 footprints on the soils of Mars. Grimzi leaves 3 prints per 6 feet, or 3/6=0.5 footprints per meter. Then over 6000 meters, Grimzi leaves 0.5*6000=<<0.5*6000=3000>>3000 footprints on the sands of Pluto. In total, the two creatures will leave 24,000+3000=<<24000+3000=27000>>27,000 footprints. #### 27,000 Steve has a bank account that earns 10% interest every year. He puts $100 in it, and then 10 each year. How much money is in it after two years? After one year it earns $10 in interest because 100 x .1 = <<100*.1=10>>10 It has $120 in it after a year because 100 + 10 + 10 = <<100+10+10=120>>120 In the second year it earns $12 in interest because 120 x .1 = <<120*.1=12>>12 In the second year it has $142 in it because 120 + 12 + 10 = <<120+12+10=142>>142 #### 142 Three plastic chairs cost as much as a portable table. Five plastic chairs cost $55. If Manny wants to buy one portable table and two chairs, how much will be left in his $100? Each plastic chair costs $55/5 = $<<55/5=11>>11. Two chairs cost $11 x 2 = $<<11*2=22>>22. A portable table costs $11 x 3 = $<<11*3=33>>33. Manny has to pay a total of $22 + $33 = $<<22+33=55>>55. Thus, Manny will be left with $100 - $55 = $<<100-55=45>>45. #### 45 Last night, Olive charged her phone for 10 hours. Assuming each hour of charge lasts the phone 2 hours of use, calculate the total time Olive would be able to use her phone before it goes off if she charges it for 3/5 of the time she charged the phone last night. If Olive charges her phone for 3/5 of the time she charged the phone last night, the phone would be charged for 3/5*10=<<3/5*10=6>>6 hours. Assuming each hour of charge lasts the phone 2 hours of use, the phone will last for 6*2=<<6*2=12>>12 hours before it goes off when Olive uses it on a six hours charge. #### 12
