Mr. Willson worked on making his furniture for 3/4 an hour on Monday. On Tuesday, he worked for half an hour. Then he worked for 2/3 an hour on Wednesday and 5/6 of an hour on Thursday. If he worked for 75 minutes on Friday, how many hours in all did he work from Monday to Friday?

Since there are 60 minutes in an hour, then Mr. Willson worked for 60 minutes x 3/4 =

<<60*3/4=45>>45 minutes on Monday. He worked for 60 minutes/2 = <<60/2=30>>30 minutes on Tuesday. He worked for 60 minutes x 2/3 = <<60*2/3=40>>40 minutes on Wednesday. He worked for 60 minutes x 5/6 = <<60*5/6=50>>50 minutes on Thursday. So Mr. Willson worked for 45 + 30 + 40 + 50 + 75 = <<240=240>>240 minutes. In hours, it is equal to 240/60 = <<240/60=4>>4 hours. #### 4 The civic league was hosting a pancake breakfast fundraiser. A stack of pancakes was $4.00 and you could add bacon for $2.00. They sold 60 stacks of pancakes and 90 slices of bacon. How much did they raise? The pancakes were $4.00 a stack and they sold 60 stacks for a total of 4*60 = $<<4*60=240.00>>240.00 The bacon was $2.00 a slice and they sold 90 slices for a total of 2*90 = $<<2*90=180.00>>180.00 They sold $240 in pancakes and $180 in bacon for a total of 240+180 = $<<240+180=420.00>>420.00 #### 420 Karen is paddling her canoe up a river against the current. On a still pond, Karen can paddle 10 miles per hour. The river flows in the opposite direction at 4 miles per hour. If the river is 12 miles long, how many hours will it take Karen to paddle up it? First find Karen's net speed by subtracting the speed of the current: 10 mph - 4 mph = <<10-4=6>>6 mph Then divide the length of the river by Karen's speed to find how long it takes her to paddle up it: 12 miles / 6 mph = <<12/6=2>>2 hours #### 2 The rate for mowing a lawn is $14 per hour. David mowed for 2 hours a day for a week. He then spent half of the money he made from mowing a lawn on a pair of shoes and gave half of the remaining money to his mom. How much money did he have left? David got $14/hour x 2 hours/day = $<<14*2=28>>28 per day from mowing. So in a week, he had $28/day x 7 days = $196. A pair of shoes cost $196/2 = $<<196/2=98>>98. David gave his mom $98/2 = $<<98/2=49>>49. The total amount he spent and gave is $98 + $49 = $<<98+49=147>>147. David is left with $196 - $147 = $<<196-147=49>>49. #### 49 Miriam takes care of the flowers in the botanical garden. She works 5 hours a day and can take care of 60 different flowers in one day. How many flowers can Miriam take care of in 6 days of work? Miriam works 5 hours per day, so in 6 days, she works 5 * 6 = <<5*6=30>>30 hours. Miriam can take care of 60 / 5 = <<60/5=12>>12 flowers per hour. In 6 days of work, Miriam can take care of 30 * 12 = <<30*12=360>>360 flowers. #### 360 In Mariam's neighborhood, there are 40 houses on one side of the main road passing through the neighborhood and three times as many homes on the other side of the road. How many homes are in Mariam's neighborhood? If the number of homes on one side of the main road is three times the number on the other side, there are 3*40 = <<3*40=120>>120 homes. In total, there are 40+120 = <<40+120=160>>160 homes in Mariam's neighborhood #### 160 Steve is holding nickels and dimes in his hand. He has 4 more dimes than nickels. He has a total of 70 cents in his hand. How many nickels is he holding? Let x be the number of nickels he is holding. His nickels are worth 5 * x = 5x cents. He has x+4 dimes. The dimes are worth 10 * (x+4) The total worth of the nickels and dimes is 5x + 10*(x+4) = 70. 5x + 10x + 40 = 70 15x = 30 x = <<2=2>>2, Steve has 2 nickels in his hand. #### 2 Leonard and his brother Michael bought presents for their father. Leonard bought a wallet at $50 and two pairs of sneakers at $100 each pair, while Michael bought a backpack at $100 and two pairs of jeans at $50 each pair. How much did they spend in all? Two pairs of sneakers cost 2 x $100 = $<<2*100=200>>200. So, Leonard spent $50 + $200 = $<<50+200=250>>250. Two pairs of jeans cost 2 x $50 = $<<2*50=100>>100. Thus, Michael spent $100 + $100 = $<<100+100=200>>200. Therefore, they spent a total of $250 + $200 = $<<250+200=450>>450 in all. #### 450 Stacy bought two packs of printer paper for the office. Each pack has 240 sheets of paper. Her office prints 80 one-page documents per day. How many days will the printer paper last her office? Stacy bought 2 * 240 = <<2*240=480>>480 sheets of paper. At 80 pages per day, the printer paper will last her office 480 / 80 = <<480/80=6>>6 days. #### 6 Jett bought a cow from the market at $600 and took it to his farm. He spent $20 every day to buy food. He also used $500 to vaccinate and deworm the cow. If he sold the cow for $2500 after 40 days, calculate the profit he made from selling back the cow to the market. The total cost of food that the cow ate for the forty days is 40*$20 = $<<40*20=800>>800 To feed and maintain the health of the cow, the total expenses Jett used is $500+$800 = $<<500+800=1300>>1300 With the expenses, Jett used $1300+$600 = $<<1300+600=1900>>1900 on the cow. If he sold the cow at $2500, Jett made a profit of $2500-$1900 = $<<2500-1900=600>>600 #### 600
