Q: Kate has to fill 52 balloons for the party. Each balloon holds 5 gallons of air. For the first 10 minutes, she can fill the balloons at a rate of 8 gallons of air per minute. For the next five minutes, she fills them at half that rate. After that, she fills the rest of the balloons at a rate of 2 gallons of air per minute. How many minutes will it take her to fill all of the balloons?
A: She needs to fill a total of 52 * 5 = 260 gallons of air. In the first ten minutes, she fills 8 * 10 = 80 gallons of air. For the next five minutes, she fills 8 / 2 * 5 = 20 gallons of air. That leaves her with 260 - 80 - 20 = 160 gallons of air to fill. It will take her 160 / 2 = 80 more minutes to fill the rest of the balloons. The total time to fill all of the balloons is 10 + 5 + 80 = 95 minutes. The answer is 95.

Q: Celine collected twice as many erasers as Gabriel did. Julian collected twice as many erasers as Celine did. If they collected 35 erasers in total, how many erasers did Celine collect?
A: Let x represent the number of erasers Gabriel collected. Celine collected 2 * x erasers. Julian collected 2 * x * 2 = 4 * x erasers. In total, Gabriel, Celine and Julian collected x + 2 * x + 4 * x = 7 * x erasers. 7 * x = 35. x = 5. Celine collected 5 * 2 = 10 erasers. The answer is 10.

Q: Anthony and his friend Leonel read about the importance of keeping pets at home and decided to start adopting cats and dogs from the local rescue center. Anthony has 12 cats and dogs, 2/3 of which are cats. Leonel has half times as many cats as Anthony and seven more dogs than Anthony. How many animals in total do the two have?
A:
If Anthony has 12 pets, the number of cats is 2 / 3 * 12 pets = 8 cats. The number of dogs that Anthony have is 12 pets - 8 cats = 4 dogs. Leonel has 1 / 2 * 8 cats = 4 cats. If Leonel has seven more dogs than Anthony, then he has 4 dogs + 7 dogs = 11 dogs. The total number of pets the two have is 11 dogs for Leonel + 4 cats for Leonel + 4 dogs for Anthony + 8 cats for Anthony = 27. The answer is 27.
