Question: Felix is chopping down trees in his backyard. For every 13 trees he chops down he needs to get his axe resharpened. It cost him $5 to sharpen his axe. If he spends $35 on axe sharpening, at least how many trees has he chopped down?

Question: At Hank’s cafe, he sells big stack pancakes which have 5 pancakes and short stack pancakes which have 3 pancakes. If 9 customers order the short stack and 6 customers order the big stack, how many pancakes does Hank need to make?
Answer: Step-by-step reasoning process: For the short stack orders, Hank needs to make 3 x 9 = 27 pancakes. For the big stack orders, he needs to make 5 x 6 = 30 pancakes. Altogether, Hank needs to make 27 + 30 = 57 pancakes.

Question: Three train stations are 2 hours apart from one another. Kira travels from the first station to the third, taking a 30 minutes break at the second station. What's the total time, in minutes, that Kira takes to travel between the first and third station?
Answer: Step-by-step reasoning process: Travel between the three stations takes 2 + 2 = 4 hours. The total time for the journey is 4 * 60 = 240 minutes. If Kira takes a 30 - minute break, her journey takes 240 + 30 = 270 minutes.
So the answer is 270.

Question: A tomato plant has 100 tomatoes. Jane picks 1/4 of that number for use in their house. After a week, she goes back and picks 20 more tomatoes, and the following week picks twice that number. What's the total number of fruits remaining on the tomato plant?
Answer:
Step-by-step reasoning process: When she picks 1 / 4 of the number of tomatoes, she goes home with 1 / 4 * 100 = 25 tomatoes. The total number of tomatoes remaining will be 100 - 25 = 75 tomatoes. After picking 20 more tomatoes the following week, the number of tomatoes remaining is 75 - 20 = 55 tomatoes. The next week she picks twice the number she picked the previous week, that is 20 * 2 = 40 tomatoes. The total number of tomatoes remaining after the final picking is 55 - 40 = 15 tomatoes.
So the answer is 15.
