Question

Sophia’s school took a field trip. A total of 21 vehicles were needed for the trip. Some students took the bus,
and some students car-pooled. There were 30 people on each bus and 4 people in each car. 318 people
altogether attended the trip. How many buses and cars were needed

Answer 1

Answer:number of bus is 9 and car is 12

Step-by-step explanation:let the no. of bus be x and no. of car be y

Also x+y=21

Y=21-x

Also

30x+4y=318

30x+4(21-x)=318

30x+84-4x=318

26x=318-84

X=234÷26

X=9

Y=21-x

y=21-9=12

Answer 2

9 buses and 12 cars.
