Melvin is helping his teachers plan a field trip. There are 255 people going on the field trip and each school bus holds 56 people. what is the minimum number of school buses they would need to reserve the trip?
a. Divide the number of people by the number that fit on one bus: 136 ÷ 51 = 2.667. They need more than 2 buses, but not quite 3. Since they can’t order part of a bus, they will need to order 3 buses.
