Kiarra is twice as old as Bea. Job is 3 times older than Bea. Figaro is 7 years older than Job. Harry is half as old as Figaro. If Kiarra is 30, how old is Harry?
Bea is 30 / 2 =
<<30/2=15>>15 years old Job is 15 * 3 = <<15*3=45>>45 years old Figaro is 45 + 7 = <<45+7=52>>52 years old Harry is 52 / 2 = <<52/2=26>>26 years old #### 26 Wally buys bears at the park. A bear is priced at $4.00 for the first bear and a discount of 50 cents per bear is given after that. How much does Wally pay for 101 bears? If the price of an additional bear drops by fifty after the first purchase, the price of each additional bear is $4.00 - $0.50 = $<<4-0.5=3.50>>3.50 Since Wally bought 101 bears, he was charged fifty cents less on 101-1 = <<101-1=100>>100 bears. The total cost for the 100 bears is 100*$3.50 = $<<100*3.5=350>>350 For the 101 bears, Wally paid a total of $350+$4 = $<<350+4=354>>354 #### 354 Out of the 120 people who attended the party, 1/3 are men while half are women. The rest are children. How many children attended the party? There were 120/3 = <<120/3=40>>40 men at the party. There were 120/2 = <<120/2=60>>60 women at the party. So, there were 40 + 60 = <<40+60=100>>100 men and women at the party. Thus, 120 - 100 = <<120-100=20>>20 were children. #### 20 Joe buys 3 oranges, 7 juices, 3 jars of honey, and 4 plants at the market. The fruit costs $4.50 each, the juice was 50 cents each, the jars of honey were $5, and the plants were 2 for $18. How much does Joe spend at the market? Joe spends 4.50*3 = <<4.50*3=13.50>>13.50 on oranges. Joe spends 7*0.5 = <<7*0.5=3.50>>3.50 on juice. Joe spends 3*5 = <<3*5=15>>15 on honey. Each plant costs 18/2 = <<18/2=9>>9 dollars. Joe spends 9*4 = <<9*4=36>>36 on plants. Joe spends a total of 13.50+3.50+15+36 = <<13.50+3.50+15+36=68>>68 dollars at the market. #### 68 Vincent has 72 inches of rope that he wants to use for a project, but he needs to cut it into smaller pieces first. He cuts it into 12 equal length pieces, but then he realizes it's too short, so he ties three pieces together. The knots then make each piece 1 inch shorter. How long are his pieces of rope after all this? Each small piece is 6 inches because 72 / 12 = <<72/12=6>>6. Each piece is then 5 inches long after the knots are tied because 6-1=<<5=5>>5 The three pieces tied together are now 15 inches long because 5 x 3 = <<5*3=15>>15 #### 15 Last year, the school library purchased 50 new books. This year, it purchased 3 times as many books. If the library had 100 books before it purchased new books last year, how many books are in the library now? Last year, there were a total of 100 + 50 = <<100+50=150>>150 books in the library. The library purchased 50 x 3 = <<50*3=150>>150 books this year. Therefore, the library now has a total of 150 + 150 = <<150+150=300>>300 books. #### 300 The Franzia wine is three times as old as the Carlo Rosi, while the Carlo Rosi is four times older than the Twin Valley. Calculate the total age of the three brands of wine if the Carlo Rosi is 40 years old. If the Franzia wine brand is three times as old as the Carlo Rosi, then the Carlo Rosi is 3*40 = <<3*40=120>>120 years old. The total number of years the Carlo Rosi and the Franzia wine brands have been around is 120+40 = <<120+40=160>>160 years The Carlo Rosi is four times older than the Twin Valley wine brand, meaning the Twin valley wine brand is 40/4 = <<40/4=10>>10 years old. Together, the three bands have a total of 10+160 = <<10+160=170>>170 years of existence. #### 170 Bella is making bracelets for her 6 friends. She needs 8 beads per bracelet. She has 36 beads. How many more beads does she need to make all six bracelets? Bella needs a total of 8 beads x 6 friends = <<8*6=48>>48 beads. She needs 48 beads – 36 beads = <<48-36=12>>12 more beads. #### 12 Arthur has $200 in his wallet. He spends four-fifths of that. How much does he have left? Arthur spent 4/5 * $200 = $<<4/5*200=160>>160. Thus he has $200 - $160 = $<<200-160=40>>40 remaining. #### 40 Jonas is a book collector. He has so many books he is converting his third bedroom into a library. This room has 400 square feet of space. He plans to put several bookshelves in the room and each bookshelf takes up 80 square feet of space. If he reserves 160 square feet of space to use for a desk and some walking space, how many shelves can he put in the room? If he reserves 160 sq. ft. of space for a desk and some walking space, then he will have 400-160=<<400-160=240>>240 sq. ft. of space remaining. If each bookshelf takes up 80 sq. ft. of space, then 240 sq ft can contain 240/80=<<240/80=3>>3 bookshelves. #### 3
