When solving word problems involving inequalities, the key is to identify phrases like '살 수 있다' (can buy) or '이내로 살 수 있다' (can buy within) and translate them into '≤' (less than or equal to) symbols, as these phrases indicate that the total cost must not exceed the available budget. For example, if a candy costs 300 won and you have 1000 won, the inequality 300x ≤ 1000 represents that the total cost of x candies must be less than or equal to 1000 won.
