Answer:


Step-by-step explanation:

Let x be the number of buses and y be the number of vans.

We know that there are 5 more buses than vans, therefore, we can set up:

x=y+5

Since a bus transports 55 people and a van transports 12 people, therefore, we can set up:

55x+12y = 409\\

Now lets solve the above two equations together by substitution

55(y+5)+12y = 409\\\\55y+275+12y=409\\\\67y+275=409\\\\67y=409-275\\\\67y=134\\\\y=2,x=2+5=7

Total number of students and teachers who rode to the zoo in buses=55*7=385

Total number of students and teachers who rode to the zoo in vans=12*2=24
