Question

A class of 195 students went on a field trip. They took 7 vehicles, some cars and some buses. Find the

number of cars and the number of buses they took if each car holds 5 students and each bus hold 45
students.

Answer 1

x-cars

y-buses

x+y=7->5x+5y=35 because both sides multiply by 5

5x+45y=195

5x+5y=35 -> 40y=160 y=4 so,x=7-y=3

the answer is 4 buses and 3 cars

Answer 2

4 buses 3 cars
