Omar buys a 12-ounce cup of coffee every morning on the way to work. On the way to work, he drinks one-quarter of the cup. When he gets to his office, he drinks another half of the cup. He forgets to drink any more of his coffee once he starts working, and when he remembers his coffee, he only drinks 1 ounce of the remaining amount because it is cold. How many ounces will be left in the cup afterward?

Omar drinks 1/4 * 12 = 12/4 =

<<12/4=3>>3 ounces on the way to work. Omar drinks 1/2 * 12 = 12/2 = <<12/2=6>>6 ounces when he gets to his office. When he drinks 1 ounce more, he will have drunk 3 + 6 + 1 = <<3+6+1=10>>10 ounces. Thus, there will be 12 - 10 = <<12-10=2>>2 ounces left in the cup afterward. #### 2 June's mom promises to pay her 1 cent for every cloverleaf she picks from the lawn. June picks 200 clovers in total. 75% have 3 petals. 24% have two petals and 1% have four petals. How many cents does June earn? There are 150 clovers with 3 leaves because 200 times .75 equals <<200*.75=150>>150. There are 48 clovers with 2 leaves because 200 times .24 equals <<200*.24=48>>48. There are 2 clovers with 4 leaves because 200 times .01 equals <<200*.01=2>>2. The four-leaf clovers are worth 450 cents because 150 times 3 equals <<150*3=450>>450 The two leafed clovers are worth 96 cents because 48 times two equals <<48*2=96>>96 The four-leaf clovers are worth 8 cents because 4 times 2 equals <<4*2=8>>8. The clovers are worth 554 cents because 450 plus 96 plus 8 equals <<450+96+8=554>>554 #### 554 Ann can skate 6 miles an hour. Her friend Glenda can skate 8 miles an hour. If they start in the same place and skate in straight lines in opposite directions for 3 hours, how many miles apart do they end up? First find how far Glenda goes in 3 hours by multiplying her speed by the number of hours she travels: 3 hours * 8 miles/hour = <<3*8=24>>24 miles Then do the same thing for Ann: 3 hours * 6 miles/hour = <<3*6=18>>18 miles Now add the number of miles both people skated to find the total distance between them: 18 miles + 24 miles = <<18+24=42>>42 miles #### 42 The fifth grade class at Rosa Parks Elementary School is holding a food drive. Half the students in Ms. Perez's class collected 12 cans each, two students didn't collect any, and the remaining 13 students students each collected 4 cans. If Ms. Perez's class has 30 students, how many cans did they collect total? Then find how many students in Ms. Perez's class collected 12 cans each: 30 students / 2 = <<30/2=15>>15 students Then find how many cans the students who collected 12 cans each collected in total: 15 students * 12 cans/student = <<12*15=180>>180 cans Then find how many cans the students who collected 4 cans each collected in total: 13 students * 4 cans/student = <<4*13=52>>52 cans Then add both amounts of cans to find the total: 180 cans + 52 cans = <<180+52=232>>232 cans #### 232 Bill milked his cow and got 16 gallons of milk. He turned 1/4 into sour cream, 1/4 into butter, and kept the rest as whole milk. It takes 4 gallons of milk to make one gallon of butter and 2 gallons of milk to make 1 gallon of sour cream. If Bill sells butter for $5/gallon, sour cream for $6/gallon, and whole milk for $3/gallon, how much money does he make? First find how much milk Bill turned into sour cream and butter: 16 gallons * 1/4 = <<16*1/4=4>>4 gallons Then find how many gallons of butter he makes out of 4 gallons of milk: 4 gallons milk / 4 gallons milk/1 gallon butter = <<4/4/1=1>>1 gallon butter Then find how many gallons of sour cream he makes out of 4 gallons of milk: 4 gallons milk / 2 gallons milk/1 gallon sour cream = <<4/2/1=2>>2 gallon sour cream Then subtract the amount of milk turned into butter and sour cream to find the remaining amount of whole milk: 16 gallons - 4 gallons - 4 gallons = <<16-4-4=8>>8 gallons Then multiply the number of gallons of milk by the price of milk to find the total cost of the milk: 8 gallons * $3/gallon = $<<8*3=24>>24 Then multiply the number of gallons of sour cream by the price of sour cream to find the total cost of the sour cream: 2 gallons * $6/gallon = $<<2*6=12>>12 Then add the cost of the butter, sour cream and milk to find the total amount of money Bill earns: $24 + $12 + $5 = $<<24+12+5=41>>41 #### 41 Donald went to a computer store. He saw a 15% reduction in the price of the laptop he wants to buy. If the laptop originally costs $800, how much will he pay for the laptop? There was $800 x 15/100 = $<<800*15/100=120>>120. Thus, Donald will pay $800 - $120 = $<<800-120=680>>680. #### 680 Grady has 20 red numbered cubes and 15 blue numbered cubes. He gives his friend Gage 2/5 of his red numbered cubes and 1/3 of the blue numbered cubes. If Gage had 10 red numbered cubes and 12 blue numbered cubes, find the total number of cubes Gage has? Grady gave 2/5 * 20 cubes = <<2/5*20=8>>8 of his red numbered cubes to Gage. If Gage initially had 10 red numbered cubes, his total number of red numbered cubes became 10 cubes + 8 cubes = <<10+8=18>>18 cubes after Grady gave him 8 more. Grady also gave 1/3 * 15 cubes = <<1/3*15=5>>5 blue numbered cubes to Gage. This increased Gage's total number of blue numbered cubes to 12 cubes + 5 cubes = <<12+5=17>>17 cubes The total number of cubes Gage has is now 17 cubes + 18 cubes = <<17+18=35>>35 cubes #### 35 There is a group of 18 people who are ordering pizza. If each person gets 3 slices and each pizza has 9 slices, how many pizzas should they order? Each person eats 3 slices of pizza, the group in total eats 18 x 3 = <<18*3=54>>54 slices. There are 54 slices in 54 / 9 = <<54/9=6>>6 pizzas. #### 6 Dulce's father has eight orange trees on his farm. If each tree has 200 fruits and Dulce picks 2/5 of the oranges from each tree, calculate the total number of fruits remaining in all the trees. The total number of oranges in all the trees before Dulce picked any is 8 trees * 200 oranges/tree = <<8*200=1600>>1600 oranges. If each orange tree has 200 oranges, and Dulce picks 2/5 of each tree's oranges, she picks 2/5 * 200 oranges = <<2/5*200=80>>80 oranges. Since the total number of orange trees is eight, Dulce picked 8 trees * 80 oranges/tree = <<8*80=640>>640 oranges from all the trees. After picking 640 oranges from the trees, the total number of oranges remaining became 1600 oranges - 640 oranges = 960 oranges. #### 960 Robby doesn't like the color brown and will not eat the brown M&M's. On his first bag, he sets aside 9 brown M&M's. On the second bag, he sets aside 12. On his third & fourth bag, there are 8 brown M&M's that he doesn't eat. On his fifth bag, there are only 3 brown M&M's that he doesn't eat. What's the average number of brown M&M's in a bag? Out of 5 bags, he had 9+12+8+8+3 = <<9+12+8+8+3=40>>40 brown M&M's He ate 5 bags so the average number of brown M&M's per bag was 40/5 = <<40/5=8>>8 brown M&M's #### 8
