You are buying books for college. You have $450 budgeted for books. The average cost of new books is $120 and the average cost of used books is $75. Write a linear inequality to represent this situation. Let x represent the number of new books and y represent the number of used books.
450 < 120x + 75y
450 > 120x + 75y
450 ≥ 120x + 75y
450 ≤ 120x + 75y
