Q: After eating half of the number of fruits he had, Martin remained with twice as many oranges as limes. If he has 50 oranges now, how many fruits did he initially have?
A: Since the number of oranges that Martin has now is twice the number of limes, there are 50 / 2 = 25 limes. The number of fruits she has now is 50 oranges + 25 limes = 75. If she had eaten half of the number of fruits that she had, initially Martin had 2 * 75 = 150 fruits. The answer is 150.
Question: Carter has a 14-hour road trip. He wants to stop every 2 hours to stretch his legs. He also wants to make 2 additional stops for food and 3 additional stops for gas. If each pit stop takes 20 minutes, how many hours will his road trip become?
Answer: He has a 14 - hour trip and wants to stop every 2 hours so that's 14 / 2 = 7 pit stops. He will make 7 pit stops plus 2 more for food and 3 more for gas for a total of 7 + 2 + 3 = 12 pit stops. Each pit stop will take 20 minutes and he is making 12 stops so that's 20 * 12 = 240 minutes. 60 minutes are in an hour and he's adding 240 minutes to his trip so that's 240 / 60 = 4 more hours. His trip started as 14 hours and he will add an additional 4 hours in pit stops for a total of a 14 + 4 = 18 hour long trip. The answer is 18.

Q: Isabelle gets a job so she can save enough money to go to a concert with her two brothers. Her ticket costs $20. Her brothers both get the children’s discount, and each of their tickets cost $10. Her brothers have saved $5 between the two of them and Isabelle has saved $5. If her job pays $3 per week, how many weeks must she work to afford the tickets?
A: The tickets for both of her brothers will cost her $10 * 2 = $20. To buy tickets for all of them, it will cost Isabelle $20 + $20 = $40. Between all of them, they have saved a total of $5 + $5 = $10. Since they have already saved $10, she needs to earn an additional $40 - $10 = $30 to afford the tickets. Since she makes $3 per week, it will take her $30 / ($3 / week) = 10 weeks to save enough money for all of the tickets. The answer is 10.
