Jim and his Cousin are out at a restaurant. They each order a cheeseburger and milkshake. They also split an order to cheese fries. A cheeseburger is $3. A milkshake is $5. Cheese fries are $8. They spend 80% of their combined money. If Jim brought $20 how much did his cousin bring?

They spent $8 each on cheeseburgers and milkshakes because 3 + 5 =

<<3+5=8>>8 They spent $16 on these items in total because 2 x 8 = <<2*8=16>>16 They spent $24 on their meal because 16 + 8 = <<16+8=24>>24 They had $30 to start because 24 / .8 = <<24/.8=30>>30 His cousin had $10 because 30 - 20 = <<30-20=10>>10 #### 10 Snap, Crackle, and Pop spend $150 on cereal in a grocery store. Snap spends twice as much as Crackle. Crackle spends 3 times as much as Pop. How much did Pop spend? Let x represent the amount that Pop spent in $ Crackle: 3x Snap:2(3x)=6x x+3x+6x=150 10x=150 x=15 #### 15 5/8 of shoppers at All Goods Available store prefer to avoid the check-out line on weekends and instead go through the express lane. If the number of shoppers in the store is 480, calculate the number of shoppers who pay at the check-out lane. At the store, 5/8 of shoppers prefer to avoid the check-out line, a total of 5/8*480 = <<5/8*480=300>>300 The total number of shoppers at the store is 480; those who prefer the check-out line is 480-300 = <<480-300=180>>180 #### 180 Tim has to go to the doctor for a sporting injury. He gets an MRI which costs $1200. The doctor needs to examine it for 30 minutes and charges $300 per hour. There is also a $150 fee just for being seen. Insurance covered 80% how much did he pay? The doctor charged 300/2=$<<300/2=150>>150 So the total cost was 150+150+1200=$<<150+150+1200=1500>>1500 The insurance covered 1500*.8=$<<1500*.8=1200>>1200 So he paid 1500-1200=$<<1500-1200=300>>300 #### 300 James goes to pet smart to adopt a puppy. The adoption fee is $200 and his friend agrees to pay 25% of that. How much does James have to pay? His friend agrees to pay 200*.25=$<<200*.25=50>>50 So he needs to pay 200-50=$<<200-50=150>>150 #### 150 If Jade earns $1600 per month and spent 75% of it on living expenses, one-fifth on insurance, and saves the rest, how much does she save per month? Jade spends $1600 x 75/100 = $<<1600*75/100=1200>>1200 for living expenses. She spends $1600 x 1/5 = $<<1600*1/5=320>>320 for insurance. She spends a total of $1200 + $320 = $<<1200+320=1520>>1520 for living expenses and insurance. So, she saves $1600 - $1520 = $<<1600-1520=80>>80 per month. #### 80 Tom dances 4 times a week for 2 hours at a time and does this every year for 10 years. How many hours did he dance? He dances 4*2=<<4*2=8>>8 hours per week He dances for 52*10=<<52*10=520>>520 weeks So in total he danced for 8*520=<<8*520=4160>>4160 hours #### 4160 Oliver had 135 stickers. He used 1/3 of his stickers, gave 2/5 of the remaining to his friend, and kept the remaining stickers. How many stickers did he keep? Oliver used 1/3 x 135 = <<1/3*135=45>>45 stickers. So, there were 135 - 45 = <<135-45=90>>90 stickers remaining. His friend received 2/5 x 90 = <<2/5*90=36>>36 stickers. Therefore, Oliver kept 90 - 36 = <<90-36=54>>54 stickers. #### 54 Patrick has been saving money to buy a bicycle that costs $150. He saved half the price but he then lent $50 to his friend. How much money does Patrick have now? Half of the price of the bicycle is 150 / 2 = $<<150/2=75>>75. The money that Patrick has now is 75 – 50 = $<<75-50=25>>25. #### 25 Peter has 15 birds. 1/3 are ducks. The rest are chickens and require special feed that costs $2 per bird. How much does it cost to feed the chickens? 2/3 of the birds are chickens because 1 -(1/3)=2/3 He has 10 chickens because 15 x (2/3) =<<15*(2/3)=10>>10 It will cost $20 to feed them because 10 x 2=<<10*2=20>>20 #### 20
