A building code allows a maximum of 140 people in a meeting room. There is one large table in the room, along with some small tables. When filled, the large table seats 15 people, and the small tables each seat 5 people. Which of the following can be used to find t, the greatest number of small tables that can be filled when the large table is also filled?

5t + 15 ≥ 140

15t + 5 ≥ 140

5t + 15 ≤ 140

15t + 5 ≤ 140
