Question

A high school student is organizing a car wash fundraiser. They spend a flat fee of $25 on a permit and a cost of $3 per car for soap and water supplies. They have a total budget of $100 to cover initial costs. What is the maximum number of cars they can wash without exceeding their budget?

GPT-5 mini · Answer

Let x be the number of cars. Cost is 25 + 3x ≤ 100.  
3x ≤ 75 → x ≤ 25.

Maximum number of cars = 25 (cost = 25 + 3·25 = $100).
