[Question]Nalani had two female dogs that were expecting and after a month gave birth to 10 puppies each. She then sold 3/4 of the puppies after they came of age, each at $200. Calculate the total amount of money she received from the sale of the puppies.
[Answer]If the two expectant dogs gave birth to 10 puppies each, the total number of puppies Nalani had is 10 + 10 = 20. When they came of age, Nalani sold 3 / 4 of the dogs, a total of 3 / 4 * 20 = 15 dogs. If each dog sold for $200, Nalani received 15 * 200 = $3000 from the sale of the dogs. The answer is 3000.

Question: Chuck can ride the merry-go-round 5 times longer than Dave who can only ride it for 10 minutes before getting sick. Erica can stay on the merry-go-round 30% longer than Chuck before getting sick. How long can Erica stay on the merry-go-round?
Answer: Dave can ride the merry - go - round for 10 minutes and Chuck can ride 5 times longer than Dave so he can ride for 10 * 5 = 50 minutes. Erica can stay on 30% longer than Chuck who can ride for 50 minutes so that's an extra .30 * 50 = 15 minutes. Chuck can ride for 50 minutes and Erica can ride an extra 15 minutes for a total of 50 + 15 = 65 minutes. The answer is 65.

[Question]Emery's family decides to travel for a weekend trip. They drive the first 100 miles in 1 hour. They stop at a McDonald's and then continue the rest of the journey for 300 miles. What's the total number of hours they traveled?
[Answer]
If the first 100 miles took one hour, then let's say the next 300 miles took x hours. if 100 miles = 1 hour, then 300 miles = x. To find the number of hours traveled for the 300 miles, x = 300 * 1 / 100. x = 3 hours. The total number of hours will be 3 + 1 = 4 hours. The answer is 4.
