Question

There are 347 students going on a field trip. Each bus holds 44 students. If each bus costs $95, is the total cost of the buses more than $1000? How can you decide without using division.

Answer 1

No the total cost would be less than $1000

Answer 2

If 10 buses are going:
Cost: $95 * 10
= $950, which is less than $1000.

44 * 10 = 440 students, which is more than enough.

The total cost is less than $1000 because overestimating the amount of buses going gives an answer of less than $1000, meaning that it is too much for the amount of students going on a field trip.
