Express your answer as a linear inequality with appropriate nonnegative restrictions.
Labor costs for a farmer are $50 per acre for corn and $40 per acre for soybeans. How many acres of each corps should the farmer plant if she wants to spend no more than $5,500 on labor? (x is the number of acres for corn and y in the number of acres for soybeans)

	1.	50x + 40y ≤ 5,500, x ≥ 0, y ≥ 0.
	2.	50x + 40y ≥ 5,500, x ≥ 0, y ≥ 0.
	3.	90x ≥ 5,500, x ≥ 0, y≥0.
	4.	90(x +y) ≤ 5,500, x ≥ 0, y ≥ 0.
