Solve the inequality for n, just like you would an equation. Since it's greater than or EQUAL to, whatever you get for n is the answer. Subtract 12 from both sides, then divide both sides by 2.

18 years ago

Sometimes it's easier to rewrite the inequality with the variable (y) on the left side. When you do this make sure you change the direction of the sign. Your work must have been correct to give you 4, but it's all numbers less than. 6.1 + 0.6y < 8.5 0.6y...
