You are given a mathematical question described with an open-ended vocabulary. Questions in this task involve real-world situations, describing a mathematical problem. You are also given 4 or 5 answer options (associated with "A", "B", "C", "D", "E"). Do not generate anything else apart from one of the following characters: 'A', 'B, 'C', 'D', 'E'. LaTeX mathematical format (the standard way to express mathematical expressions in the typesetting software known as LaTeX) is used to express equations. Each question is solvable with high school math knowledge. Give only one answer for each question.

Input: Consider Input: The daily cost of running a certain air conditioner is 12 cents per hour for the first 8 hours and 10 cents per hour for each additional hour over 8 hours. Which of the following expressions represents the cost, in dollars, of running this air conditioner for h hours each day, for 90 days, if \(8 < h < 24\)?
(A)\(90(0.12) + 9(h - 8)\) (B)\(90(0.12)h + h - 8\) (C)\(90(0.12)h + 9(h - 8)\) (D)\(90(0.12)(8) + 9(h - 8)\) (E)\(90(0.12)(8) + (h - 8)\)

Output: D


Input: Consider Input: If \(p\) items can be purchased for 60 dollars, how many items can be purchased for \(w\) dollars?

Output: A


Input: Consider Input: At Essex High School 100 students are taking chemistry and 80 students are taking are biology. If 20 students are taking both chemistry and biology, what is the ratio of the number of students taking only chemistry to the number taking only biology?
(A)\(\frac { 3 } { 4 } \) (B)\(\frac { 4 } { 5 } \) (C)\(\frac { 1 } { 1 } \) (D)\(\frac { 5 } { 4 } \) (E)\(\frac { 4 } { 3 } \)


Output: E
