Aclass of 222 students went on a field trip. they took 9 vehicles, some cars and some me buses. find the number of cars and the number of busses they took if each car holds 4 students and each bus holds 35 students

There were 3 cars and 9 buses used for the field trip.

Step-by-step explanation:

Let the number of cars be x

and Number of buses be y.

Total number of vehicles used = 9

Hence,

Also

Each Car carries students = 4

Each Bus carries students = 35

Total Students = 222

Hence,

Now multiplying equation 1 by 4 we get;

Now Subtracting equation 3 from equation 2 we get;

Now y = 6

∴ x + y = 9 (Given)

x + 6 = 9

x = 9 - 6

x = 3

Hence, There were 3 cars and 9 buses used for the field trip.
