Question

All 136 students in the Math Club went on a field trip. Some students rode in vans which hold 8

students each and some students rode in buses which hold 40 students each. How many of each
type of vehicle did they use if there were 5 vehicles total?

Answer 1

Answer: 3 buses, 2 vans
Explanation: let x be number of buses, y be number of vans,
136= 40x+8y
5=x+y
Use simultaneous equation,
136-8(5)= 40x +8y - 8(x+y)
96= 32x
x = 3
When x=3, y= 2
