[Question]James is trying to create a new breed of kittens with extra-long tails. Each generation of kittens he breeds has a tail 25% longer than the last generation. If the first generation has tails 16 cm long, how long are the third generation's tails?
[Answer]First find how much longer the second generation's tails are: 25% * 16 cm = 4 cm. Then add that length to the first generation's tail length to find the second generation's tail length: 4 cm + 16 cm = 20 cm. Then find how much longer the third generation's tails are: 25% * 20 cm = 5 cm. Then add that length to the second generation's tail length to find the third generation's tail length: 5 cm + 20 cm = 25 cm. The answer is 25.
Q: Out of the 400 emails that Antonia received in her mail, 1/4 were spam emails, while 2/5 of the remaining emails were promotional messages. If the rest of the emails were important emails, calculate the total number of important emails in her inbox.
A: Out of the 400 emails, 1 / 4 * 400 = 100 emails were spam emails. The number of emails that were not spam emails is 400 - 100 = 300. 2 / 5 of the emails which were not spam were promotional emails, a total of 2 / 5 * 300 = 120 emails. If the rest of the emails were important emails, there were 300 - 120 = 180 important emails. The answer is 180.
Question: Paula has 20 candies to be given out to her six friends. She needs to buy four additional candies so she can give an equal number of candies to her friends. How many candies will each of her friends get?
Answer: Paula will have a total of 20 + 4 = 24 candies. Thus, each of her friends will receive 24 / 6 = 4 candies. The answer is 4.
[Question]Carl is figuring out how much he'll need to spend on gas for his upcoming road trip to the Grand Canyon. His car gets 30 miles per gallon in cities and 40 miles per gallon on the highway. The distance from his house to the Grand Canyon, one way, is 60 city miles and 200 highway miles. If gas costs $3.00 per gallon, how much will Carl need to spend?
[Answer]First figure out how many city miles Carl will drive round trip by multiplying the one - way number of city miles by 2: 60 miles * 2 = 120 miles. Then figure out how many highway miles Carl will drive round trip by multiplying the one - way number of highway miles by 2: 200 miles * 2 = 400 miles. Now divide the round - trip number of city miles by the number of city miles per gallon Carl's car gets: 120 miles / 30 mpg = 4 gallons. Now divide the round - trip number of highway miles by the number of highway miles per gallon Carl's car gets: 400 miles / 40 mpg = 10 gallons. Now add the gallons for the highway miles and the city miles to find the total number of gallons Carl needs to buy: 10 gallons + 4 gallons = 14 gallons. Finally, multiply the number of gallons Carl needs to buy by the cost per gallon to find out how much he spends: 14 gallons * $3.00 = $42.00. The answer is 42.
Q: In Fifi's closet, she hangs all of her clothes on colored plastic hangers. She has clothes hanging on 7 pink hangers, 4 green hangers, one less blue hanger than there are green hangers, and one less yellow hanger than there are blue hangers. What is the total number of colored hangers in Fifi's closet?
A: With 4 green hangers, 1 less blue hanger than there are green hangers is 4 - 1 = 3 blue hangers. With 3 blue hangers, 1 less yellow hanger less than there are blue hangers is 3 - 1 = 2 yellow hangers. With 7 pink hangers, the total number of colored hangers in Fifi's closet is 7 + 4 + 3 + 2 = 16 hangers. The answer is 16.
Question: Five friends eat at Wendy's and ordered the following: a platter of Taco Salad that cost $10, 5 orders of Dave's Single hamburger that cost $5 each, 4 sets of french fries that cost $2.50, and 5 cups of peach lemonade that cost $2 each. How much will each of them pay if they will split the bill equally?

The cost of 5 pieces of Dave's Single hamburger is $5 x 5 = $25. The cost of 4 sets of french fries is $2.50 x 4 = $10. The cost of 5 cups of peach lemonade is $2 x 5 = $10. So, their total bill is $10 + $25 + $10 + $10 = $55. Therefore, each of them will contribute $55 / 5 = $11. The answer is 11.
