The correct answer is:
3x + 1.5y ≤ 25
Explanation:
The variable x represents the number of board games. Each one weighs 3 pounds, which gives us the expression 3x.
The variable y represents the number of remote control cars. Each one weighs 1.5 pounds, which gives us the expression 1.5y.
The sum of their weights gives us the expression 3x+1.5y.
Since the box can hold no more than 25 pounds, the inequality must be less than or equal to:
3x+1.5y≤25
