While reading in bed with his wife Susan, Charlie heard a noise at the door. It was Sarah entering the bedroom with 4 friends. If there were also 8 people in the living room, how many people are in the house?
In the bedroom, there are 1 + 1 =
<<1+1=2>>2 people in the house (Charlie and Susan). Sarah and four friends then entered, a total of 4+1 = <<4+1=5>>5 people. Together with Charlie and Susan, there are now 5+2 = <<5+2=7>>7 people in the bedroom. Since there are 8 more people in the living room, the total number of people in the house is 8 + 7 = <<8+7=15>>15 #### 15 A football club has a balance of $100 million. The club then sells 2 of its players at $10 million each, and buys 4 more at $15 million each. How much money is left in the club register in millions of dollars? The 2 players are sold for a total of 2*10 = $<<2*10=20>>20 million So the club has 100 + 20 = $<<100+20=120>>120 million The cost of buying 4 more players at $15 million each is 4*15 = $<<4*15=60>>60 million So the club now has 120 – 60 = $<<120-60=60>>60 million #### 60 Erica sees 9 butterflies in the garden. She sees one-third of them fly away. How many butterflies are left in the garden? Erica sees 9 / 3 = <<9/3=3>>3 butterflies fly away. There are 9 - 3 = <<9-3=6>>6 butterflies still left in the garden. #### 6 A bakery sells boxes of doughnuts and if there are any doughnuts left at the end of the day, the bakery gives them away. Each box of doughnuts holds 10 doughnuts and all of the doughnuts that the bakery makes are put into these boxes. The bakery makes 300 doughnuts for the day and sells 27 boxes of doughnuts throughout the day. How many doughnuts are given away at the end of the day? The bakery has made 300 total doughnuts / 10 doughnuts per box = <<300/10=30>>30 boxes of doughnuts. So at the end of the day, they still have 30 total boxes of doughnuts – 27 sold boxes of doughnuts = <<30-27=3>>3 boxes of doughnuts leftover. They are therefore giving away 3 boxes of doughnuts * 10 doughnuts per box = <<3*10=30>>30 doughnuts. #### 30 Jerry charges $20 to pierce someone's nose and 50% more to pierce their ears. If he pierces 6 noses and 9 ears, how much money does he make? First find how much more Jerry charges to pierce one person's ears than their nose: $20 * 50% = $<<20*50*.01=10>>10 Then add that amount to the cost of nose piercing to find the total cost: $10 + $20 = $<<10+20=30>>30 Then multiply that price by the number of ears he pierces to find his total earnings from ear-piercing: $30/ear * 9 ears = $<<30*9=270>>270 Then multiply the price of nose-piercing by the number of noses pierced: $20/nose * 6 noses = $<<20*6=120>>120 Then add the money from nose-piercing to the money from ear-piercing to find Jerry's total income: $120 + $270 = $<<120+270=390>>390 #### 390 There's an online sale where you get $10 for every $100 that you spend. If you make a purchase of $250 before discounts, how much did you end up paying? If for every $100 spent I save $10, then for $250 spend I'd save $10*2=$20 If my total was $250, then I ended up paying $250-$20=$<<250-20=230>>230 #### 230 At an auction event, the price of a TV, whose cost was $500, increased by 2/5 times its initial price. The price of a phone, which was $400, also increased by 40% from its original price. If Bethany had taken both items to the auction, calculate the total amount she received for the items after the sale at the auction. If the TV's original price was $500, at the auction, its price increased by 2/5*$500 = $<<2/5*500=200>>200 The total price at which the TV was sold at the auction is $500+$200 = $<<500+200=700>>700 The price of the phone also increased at the action, a 40% increase which is 40/100*$400 = $<<40/100*400=160>>160 The total price that the phone was sold for after the auction is $400+$160 = $<<400+160=560>>560 In total, the TV and the phone sold for $700+$560 = $<<700+560=1260>>1260 at the auction #### 1260 Lance wants to finish reading a 100 page book in 3 days. Yesterday, he started to read 35 pages. Today, he read 5 fewer pages than yesterday. How many pages should he read tomorrow to finish the book? Lance read 35 - 5 = <<35-5=30>>30 pages today. So he read a total of 35 + 30 = <<35+30=65>>65 pages in 2 days. Thus, he should read 100 - 65 = <<100-65=35>>35 pages tomorrow. #### 35 Megan bought 2 dozen eggs. As she was walking to her car, she dropped a tray of eggs. 3 eggs broke, and twice as many cracked. What is the difference between the eggs that are still in perfect condition and those that are cracked? 2 dozen eggs means 2 x 12 = <<2*12=24>>24 eggs 3 x 2 = <<3*2=6>>6 eggs cracked. The remaining eggs still in perfect condition is 24 - 3 - 6 = <<24-3-6=15>>15 The difference between the perfect eggs and cracked eggs is 15 - 6 = <<15-6=9>>9 eggs. #### 9 Connor is taking his date to the movies. The tickets cost $10.00 each. They decided to get the large popcorn & 2 drink combo meal for $11.00 and each grab a box of candy for $2.50 each. How much will Connor spend on his date? The tickets cost $10.00 each and he has to buy 2 tickets so that's 10*2 = $<<10*2=20.00>>20.00 They each grab a box of candy that's $2.50 a box so that will cost 2*2.50 = $<<2*2.50=5.00>>5.00 The tickets cost $20.00, the candy is $5.00 and the combo will is $11.00 so Connor will spend 20+5+11 = $<<20+5+11=36.00>>36.00 during his date #### 36
