Robby, Jaylen and Miranda are employed at a Cheesecake factory, earning $10 per hour. They work 10 hours a day, five days a week. Robby saves 2/5 of his salary, Jaylene saves 3/5 of his salary, while Miranda saves half of her salary. What are the combined savings of the three employees after four weeks?

In a day, each of them earns $10/hour * 10 hours/day = $

<<10*10=100>>100/day The total number of days each of them work in a month is five days per week * 4 weeks = <<5*4=20>>20 days If each of them earns $100 per day, in 20 days, they'll earn 20 days/month * $100/day = $<<20*100=2000>>2000/month Robby saves 2/5 * $2000 = $<<2/5*2000=800>>800 from his salary Jaylene's savings is 3/5 * $2000 = $<<3/5*2000=1200>>1200 of her salary Miranda saves 1/2 * $2000 = $<<2000*0.5=1000>>1000 from her salary. The total saving for the three employees is $1000 + $1200 + $800 = $<<1000+1200+800=3000>>3000 #### 3000 The Jacksonville Walmart normally gets 120 customer complaints per day. That number increases by 1/3rd when they're short-staffed and this increases by another 20% when the self-checkout is broken. If the store was short-staffed and the self-checkout was broken for 3 days, how many complaints does the store get? First find the number of complaints per day when the store is short-staffed: 120 complaints/day * 4/3 = <<120*4/3=160>>160 complaints/day Then find the number of complaints per day when the self-checkout is broken and they're short-staffed: 160 complaints/day * 1.2 = <<160*1.2=192>>192 complaints/day Then multiply the number of complaints per day by the number of days to find the total number of complaints: 192 complaints/day * 3 days = <<192*3=576>>576 complaints #### 576 Louis has 5 oranges and 3 apples. Samantha has 8 oranges and 7 apples. If Marley has twice as many oranges as Louis and three times as many apples as Samantha, how many fruits in total does Marley have? Marley has twice as many oranges as Louis (who has 5 oranges) for a total of 2*5 = <<2*5=10>>10 oranges He also has thrice as many apples as Samantha (who has 7 apples) for a total of 3*7 = <<3*7=21>>21 apples Marley has a total of 10+21 = <<10+21=31>>31 fruits #### 31 Farmer Steven needs to load his truck up with compost. His tractor can scoop up compost at a rate of 75 pounds per minute. Steven's son, Darrel, wants to help. Using a shovel, Darrel can scoop up 10 pounds per minute. How much time, in minutes, would it take for the two working together at the same time to load up 2550 pounds of compost into the truck? Working together at the same time, the rate at which the two would be able to load compost would be 75+10=<<75+10=85>>85 pounds/minute. At 85 pounds/minute, the 2550 pounds could be loaded in 2550/85=<<2550/85=30>>30 minutes. #### 30 Mia has $20 more than twice as much money Darwin has. If Darwin has $45, how much money does Mia have? Twice the money of Darwin is 2 * $45 = $<<2*45=90>>90. The money that Mia have is $20 + $90 = $<<20+90=110>>110. #### 110 Ivan buys 48 apples to make 24 full-size pies. He ends up not using as many as he thought because he decides to make mini pies instead of full-size ones, which only use 1/2 an apple each. If Ivan bakes 24 mini pies, how many apples does he have leftover? Ivan wants to bake 24 pies which use 1/2 an apple each, 24 pies x 1/2 apple each = <<24*1/2=12>>12 apples Ivan uses 12 of his 48 apples, 48 - 12 = 36 apples Ivan has 36 apples leftover. #### 36 James prints out 2 books. They are each 600 pages long. He prints out double-sided and 4 pages per side. How many sheets of paper does he use? He printed 600*2=<<600*2=1200>>1200 pages Each sheet of paper was 4*2=<<4*2=8>>8 pages So he used 1200/8=<<1200/8=150>>150 sheets of paper #### 150 John has been having trouble sleeping lately. In the past week he was only able to get 3 hours of sleep on 2 of the days and on the remaining days he was only able to get 60% of the recommended 8 hours of sleep. How much sleep did he get this week? For the 2 days he gets 2*3=<<2*3=6>>6 hours He gets 60% of the recommended amount for 7-2=5 days On those days he gets 8*.6=<<8*.6=4.8>>4.8 hours So he gets 5*4.8=<<5*4.8=24>>24 hours So he gets a total of 24+6=<<24+6=30>>30 hours of sleep #### 30 Tracy set up a booth at an art fair. 20 people came to look at her art. Four of those customers bought two paintings each. The next 12 of those customers bought one painting each. The last 4 customers bought four paintings each. How many paintings did Tracy sell at the art fair? The first 4 customers bought 4*2=<<4*2=8>>8 paintings The next 12 customers bought 12*1=<<12*1=12>>12 paintings The last 4 customers bought 4*4=<<4*4=16>>16 paintings In total Tracy sold 8+12+16=<<8+12+16=36>>36 paintings #### 36 Cameron guides tour groups in a museum. He usually answers two questions per tourist. Today, he did four tours. The early morning first group was only 6 people. The following group was a busy group of 11. The third group had 8 people, but one was inquisitive and asked three times as many questions as usual. The last group of the day was a late group of 7. How many questions did Cameron answer? Cameron answered 2 * 6 = <<2*6=12>>12 questions for the first group. He answered 2 * 11 = <<2*11=22>>22 questions for the second group. The third group had 8 - 1 = 7 tourists that asked 2 questions each. The third group also had 1 tourist that asked 2 * 3 = <<1*2*3=6>>6 questions. Thus, the third group asked 7 * 2 + 6 = 14 + 6 = <<7*2+6=20>>20 questions. The last group asked 7 * 2 = <<7*2=14>>14 questions. For all four tours, Cameron answered 12 + 22 + 20 + 14 = <<12+22+20+14=68>>68 questions. #### 68
