The organizers at a job fair purchase plastic cups for serving refreshments to attendees. The organizers expect at least 1,700 a
ttendees, and they must ensure a sufficient number of cups. The cups arrive packed in cartons. The number of cups in each carton is 5 more than four times the number of cartons. Which of the following inequalities can be used to determine c, the number of cartons of cups purchased?
Let c be the number of cartons of cups purchased. Since the number of cups in each carton is 5 more than four times the number of cartons, then the number of cups is 4c+5.
The organizers expect at least 1,700 attendees, then the total number of cups should be greater or equal to 1,700. This gives you the inequality
