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:
[tex]x=y+5[/tex]
Since a bus transports 55 people and a van transports 12 people, therefore, we can set up:
[tex]55x+12y = 409\\[/tex]
Now lets solve the above two equations together by substitution
[tex]55(y+5)+12y = 409\\\\55y+275+12y=409\\\\67y+275=409\\\\67y=409-275\\\\67y=134\\\\y=2,x=2+5=7[/tex]
Total number of students and teachers who rode to the zoo in buses[tex]=55*7=385[/tex]
Total number of students and teachers who rode to the zoo in vans[tex]=12*2=24[/tex]
