409 students go to the zoo using buses and vans

Question

409 students go to the zoo using busses and vans. 55 students fit in a bus and 12 students can fit in a van. There are 5 more buses than vans. How many busses and vans are needed. I don’t know how to write the equation that shows 5 more buses than vans.

Answer 1

B = V+5

55(V+5) + 12*V = 409

55V + 275 + 12V = 409

67V + 275 = 409

67V = 134

V = 2

2 vans 7 busses

2*12 + 7*55 = 24 + 385 = 409
