Mr Charles plans to buy 3 security cameras he wants to spend less than $450 on the cameras in all
Let x represent how much he wants to spend on each camera which inequality describes the problem
3x is less than or equal to 450
3 + x is less than or equal to 450
3x < 450
3 + x is less then or equal to 450
3x is less than or equal to 450

Let x represent the amount Mr. Charles wants to spend on each camera.
He wants to buy 3 cameras, so the total amount he wants to spend on all 3 cameras is 3x.
The total amount he wants to spend on all 3 cameras should be less than $450, so the inequality can be written as:
3x ≤ 450
Therefore, the correct inequality is:
3x ≤ 450
