Question: Louie sells Dodge, Hyundai, and Kia vehicles, and his company has 400 vehicles for sale on the store's parking lot. Half of the vehicles on the lot are Dodge, and there are half as many Hyundai vehicles on the lot as there are Dodge vehicles. How many Kia vehicles are on the lot?
Answer: Step-by-step reasoning process: Half of the 400 vehicles for sale on the lot are Dodges, or a total of 400 / 2 = 200 Dodge vehicles. Since there are half as many Hyundai vehicles on the lot as there are Dodge vehicles, then there are 200 / 2 = 100 Hyundai vehicles on the lot. Since the remainder of the vehicles are Kias, then there are 400 - 200 - 100 = 100 Kia vehicles for sale on the lot.
So the answer is 100.

Question: In Mr. Bolton's class of 25 students, 2/5 of the students like maths, 1/3 of the remaining students like science, and the rest of the students like history. Calculate the combined total number of students who like history and those who like maths.
Answer: Step-by-step reasoning process: If there are 25 students in the class, then 2 / 5 * 25 = 10 students like maths. The number of students who don't like math is 25 - 10 = 15 students. If 1 / 3 of the students that don't like math like science, then 1 / 3 * 15 = 5 students like science. The remaining number of students who enjoy history is 15 - 5 = 10. The combined total for the students who want history and maths is 10 + 10 = 20.
So the answer is 20.

Question: A book library charges fifty cents per day on any book borrowed by its members to read outside the library's premises. At the start of May, Celine borrowed three books from the library to read at home for her upcoming examinations. If she returned one book 20 days after borrowing it, and the other two stayed at her house until the end of May, calculate the total amount of money that she paid at the library for lending the three books.
Answer:
Step-by-step reasoning process: Celine was charged $0.50 * 20 = $10 for the book she returned to the library after 20 days. If the other two books stayed at her house until the end of May, she paid 31 * $0.50 = $15.5 for each book. For the two books that stayed at her house until the end of May, Celine paid $15.5 * 2 = $31. For the three books, Celine paid $31 + 10 = $41.
So the answer is 41.
