At the zoo, there are 5 different types of animals. Seeing each animal type takes around 6 minutes. How much time would it take to see each animal type if the zoo decided to import 4 new species?

If the zoo would decide to import 4 new species, there would be 5 + 4 =

<<5+4=9>>9 species in total. This would mean, that seeing each type of animal would take 9 * 6 = <<9*6=54>>54 minutes. #### 54 Agnes is 25 years old and her daughter, Jane is 6 years old. In how many years will Agnes be twice as old as Jane? Let the number of years after which Agnes will be twice as old as Jane be x After x years, 25+x = 2(6+x) Solving the equation by expanding and collecting like terms gives: x-2x = 12-25 Further solving gives: -x = -13 Multiplying both sides by -1 gives x = 13 #### 13 The American swallow can lift into the air and carry a maximum of 5 pounds of weight, while the European swallow can lift and carry twice the weight as the American swallow. If there was a flock of 90 swallows, containing twice as many American as European swallows, what is the maximum combined weight the flock can carry? If "x" is the number of European swallows, then, for every one European swallow, there would be 2x American swallows. Thus, the total number of swallows would be 2x+x=90 swallows Thus, the number of European swallows x=<<30=30>>30. And the number of American swallows is 90-30=<<90-30=60>>60. A European swallow can carry twice what an American swallow can carry, or 2*5=<<2*5=10>>10 pounds. 30 European swallows can carry a maximum of 30*10=<<30*10=300>>300 pounds. 60 American swallows can carry a maximum of 60*5=<<60*5=300>>300 pounds. Thus, a flock of 90 birds, with 30 European and 60 American swallows, can carry 300+300=600 pounds #### 600 Joseph had socks of many different colors. His dresser drawer was filled to overflowing with red, blue, black, and white socks. Uncertain of how many pairs he had of each color, he began to sort his socks. He discovered that he had three more pairs of blue socks than he had pairs of black socks. He had one less pair of red socks than he had pairs of white socks. He had twice as many blue socks as he had of red socks. And he counted a total of 6 red socks. What is the total number of Joseph's socks? Starting with 6 red socks, twice the number of blue socks as red meant Joseph had 2*6=12 blue socks. With one less pair of red socks than white socks, this meant 2 fewer red socks than white, for a total of 6-2=<<6-2=4>>4 white socks. Also, 12 blue socks=6 pairs of blue socks. With three more pairs of blue socks than pairs of black socks, this means he had 6-3=<<6-3=3>>3 pairs of black socks. And three pairs of black socks corresponds to 3*2=<<3*2=6>>6 black socks. Thus, in total, he had 6+12+4+6=<<6+12+4+6=28>>28 socks. #### 28 Zane purchases 2 polo shirts from the 40% off rack at the men’s store. The polo shirts are $50 each at the regular price. How much did he pay for the shirts? At regular price, the polo shirts are 2 x $50 = $<<2*50=100>>100. At 40% off, he gets a discount of , $100 x 40% = $<<100*40*.01=40>>40. With this discount, the polo shirts cost $100 - $40 = $<<100-40=60>>60. #### 60 John buys 3 dress shirts. They sell for $20 each. He also has to pay 10% tax on everything. How much did he pay in total? The shirts cost 3*$20=$<<3*20=60>>60 before tax The tax cost $60*.1=$<<60*.1=6>>6 So in total they paid $60+$6=$<<60+6=66>>66 #### 66 Simon and Peter have a big stamp collection. Simon collects red stamps and Peter collects white stamps. Simon has 30 red stamps and Peter has 80 white stamps. If the red stamps are then sold for 50 cents each and the white stamps are sold for 20 cents each, what is the difference in the amount of money they make in dollars? Red stamps are 50 cents each and for 30 stamps, Simon would get 50 * 30 = <<50*30=1500>>1500 cents White stamps are 20 cents each and for 80 stamps, Peter would get 20 * 80 = <<20*80=1600>>1600 cents The difference in cents is 1600 - 1500 = <<1600-1500=100>>100 cents One dollar equals 100 cents, so the difference in dollars is 100/100 = $<<100/100=1>>1 #### 1 A movie theatre has 250 seats. The cost of a ticket is $6 for an adult and $4 for a child. The theatre is full and contains 188 children. What is the total ticket revenue for this movie session? The number of adults present is 250 – 188 = <<250-188=62>>62 adults The revenue generated by adults is 62 * 6 = $<<62*6=372>>372 The revenue generated by children is 188 * 4 = $<<188*4=752>>752 So the total ticket revenue is 372 + 752= $<<372+752=1124>>1124 #### 1124 Lilibeth and her friends go strawberry picking. Lilibeth fills 6 baskets where each basket holds 50 strawberries. If three of Lilibeth's friends pick the same amount as her, how many strawberries do Lilibeth and her friends pick in all? Lilibeth picks 6 x 50 = <<6*50=300>>300 strawberries. There are 1 + 3 = <<1+3=4>>4 of them who are picking strawberries. Therefore, they pick a total of 300 x 4 = <<300*4=1200>>1200 strawberries. #### 1200 Iris has a berry farm. Her brother and sister help her to pick up the berries and sell them to the market. Iris picked 30 blueberries, her sister picked 20 cranberries, and her brother was able to pick 10 raspberries. If 1/3 of the total berries they were able to pick are rotten and the remaining 1/2 of the fresh berries need to be kept, how many berries will they be able to sell? Iris and his brother and sister were able to pick a total of 30 + 20 + 10 = <<30+20+10=60>>60 berries. The rotten berries that needed to be thrown away are (1/3) x 60 = <<(1/3)*60=20>>20. So, the total number of fresh berries is 60 - 20 = <<60-20=40>>40. The berries they need to keep are (1/2) x 40 = <<(1/2)*40=20>>20. Therefore, the total number of berries they will be able to sell is 40 - 20 = <<40-20=20>>20. #### 20
