Question

The sophomore class at JMHS planned a field trip to Fiesta Texas. To transport the 240 students whoare going, the class rents 8 vans and 8 buses. The junior class at JMHS also wants to go on this trip thefollowing week. To transport all the 54 students who plan to go, the juniors rent 4 vans and 1 bus. Ifeach bus and each van is filled to capacity on both trips, how many students can ride in each bus?

Answer 1

Problem info

Sophomore

total =T= 240 students

V= 8 vans and B= 8 buses

Juniors

total=T=54 students

V=4 vans and B= 1 bus

Solution

Let v the numbers of kids in vans and b the number of kids in bus we can set up these equations:

`8v+8b=240`
`4v+b=54`

We can solve for b from the second equation and we got:

`b=54-4v`

And we can replace at equation 1 and we got:

`8v+8(54-4v)=240`

And we can solve for v and we got:

`-24v=-192`
`v=(192)/(24)=8`

And solving for b we got:

`b=54-4(8)=22`

Each van with 8 kids

Each bus with 22 kids
