The total ticket cost is (15x+40) rupees and it should be at most (250) rupees. What is the solution for (x)?

Answer and explanation

Correct answer: \(x\le 14\)

“At most 250 rupees” means \(15x+40\le250\). Subtracting 40 from both sides gives \(15x\le210\). Since 15 is positive, dividing by 15 does not reverse the inequality sign, so \(x\le14\). The option \(x<14\) is incorrect because \(x=14\) gives a total cost of exactly 250 rupees, which is allowed. Exam tip: translate “at most” as \(\le\).
