Tanya went to the grocery store to buy some fruit. She bought 6 pears, 4 Granny Smith apples, 2 pineapples, and a small basket of plums, which were all placed in a single paper bag. Unfortunately, the bag that the fruit had been placed in had developed a hole. Therefore, as Tanya walked home, half of the fruit fell out of the bag. When she later counted the fruit left in the bag, there were only 9 pieces remaining. How many plums did she buy?

If half of the fruit equals 9 pieces, then Tanya bought 2*9=

<<2*9=18>>18 pieces of fruit. Thus, Tanya bought 18-6-4-2=<<18-6-4-2=6>>6 plums. #### 6 Javier has a wife and 3 children. They have 2 dogs and 1 cat. Including Javier, how many legs are there in total in Javier’s household? For the humans in the house, there are 5 * 2 = <<5*2=10>>10 legs Javier has a total of 2 + 1 = <<2+1=3>>3 four-legged pets For the pets in the house, there are 3 * 4 = <<3*4=12>>12 legs There are a total of 10 + 12 = <<10+12=22>>22 legs #### 22 Tina is getting $20 for each book she sells. If she realizes a $120 profit on her sales, how many people have she sold the books to if each book costs $5 to make and every customer buys 2 at a time? First, we need to determine the profit per book. To do this, we perform 20-5=<<20-5=15>>15 dollars in profit per book. Next, we divide the total sales by the profit per book, performing 120/15=<<120/15=8>>8 books sold in total. Since the books are sold 2 at a time, we divide the number sold by 2 to find the total number of people sold to, performing 8/2=<<8/2=4>>4 people in total. #### 4 Michael loves to paint and sells his creations. He charges $100 for a large painting and $80 for a small painting. At his last art show, he sold 5 large paintings and 8 small paintings. How much did he earn in all? He earned 5 x $100 = $<<5*100=500>>500 for the large painting. And he earned 8 x $80 = $<<8*80=640>>640 for the small paintings. Therefore, he earned a total of $500 + $640 = $<<500+640=1140>>1140 in all. #### 1140 Calvin has been saving his hair clippings after each haircut to make a wig for his dog. He has gotten 8 haircuts and knows that he needs 2 more to reach his goal. What percentage towards his goal is he? His goal is 10 haircuts because 8 + 2 = <<8+2=10>>10 He is 80% there because (8 / 10) x 100 = <<(8/10)*100=80>>80 #### 80 Maria wants to buy a brand new bike. The retail price at the bike shop stands at $600. She saved $120 toward the purchase. As this was not enough, she asked her mother to give her the remaining amount. Her mother offered her $250 and told her that she needs to earn the rest working during the holidays. How much money must Maria earn to be able to buy the bike she wants? Maria has $120 and received $250 from her mother. So she has 120 + 250 = $<<120+250=370>>370. As the price of the bike stands at $600, Maria needs 600 – 370 = $<<600-370=230>>230 more to buy the bike. #### 230 Catherine had an equal number of pencils and pens. If she had 60 pens and gave eight pens and 6 pencils to each of her seven friends and kept the rest for herself, how many pens and pencils did she have left? Catherine gave eight pens to each of her seven friends, a total of 8*7 = <<8*7=56>>56 pens. She remained with 60-56 = <<60-56=4>>4 pens. When she also gave 6 pencils to each of her seven friends, she gave away 6*7 = <<6*7=42>>42 pencils. Since she had the same number of pencils as pens, she remained with 60-42 = <<60-42=18>>18 pencils. The total number of pens and pencils that Catherine remained with is 4+18 = <<4+18=22>>22 #### 22 Lao is farming chickens. He can sell each chicken for $1.50. A bag of chicken feed weighs 20 pounds and costs $2. Each chicken will need 2 pounds of feed from the time it hatches to the time he sells it. If he makes $65 profit from selling chickens, how many did he sell? A bag of feed is enough for 10 chickens because 20 / 2 = <<20/2=10>>10 Each chicken costs $.2 to raise because 2 / 10 = <<2/10=.2>>.2 Each chicken results in $1.3 of profit because 1.5 - .2 = <<1.5-.2=1.3>>1.3 He sells 50 chickens because 65 / 1.3 = <<65/1.3=50>>50 #### 50 While Greg was camping with his family for a week, it rained for 3 days. When he looked at the weather records, he saw that the amount of rain was 3 mm, 6 mm, and 5 mm on the three days. During the same week, it rained 26 mm at his house. How much less rain did Greg experience while camping? While camping there was 3 + 6 + 5 = <<3+6+5=14>>14 mm of rain in 3 days. Greg experienced 26 – 14 = <<26-14=12>>12 mm less rain at the campsite. #### 12 Timothy has $50 to spend at a souvenir shop. He sees some t-shirts that cost $8 each, key chains that sell 3 pieces for $2, and bags that cost $10 each. Timothy buys 2 t-shirts and 2 bags. How many pieces of key chains can he buy with the amount of money he has left? The two t-shirts amount to $8 x 2 = $<<8*2=16>>16. The two bags amount to $10 x 2= $<<10*2=20>>20. So Timothy spent $16 + $20 = $<<16+20=36>>36 for the shirts and bags. He still has $50 - $36 = $<<50-36=14>>14 left to spend for the key chains. With the money, he can buy $14/$2 = <<14/2=7>>7 sets of key chains. Therefore, he can buy 7 x 3 = <<7*3=21>>21 pieces of key chains. #### 21
