The junior and senior classes are taking a field trip to Telluride. There are 944 students going. Students will ride in school
vans which carry 8 passengers and on schools buses which carry 40 passengers. There are a total of 42 vehicles
How many vans need to be driven? How many school buses will be driven?
a. Write a system of linear equations to represent the situation (don't forget to define the variables).
b. Solve the system by substitution.

23 school vans and 19 school buses

Step-by-step explanation:

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

1.  There are a total of 42 vehicles, so

2. Students will ride in school vans which carry 8 passengers, so in x vans there will be passengers and on schools buses which carry 40 passengers, so in y buses there will be passengers. There are 944 students going. Therefore,

a. You get the system of two equations:

b. From the first equation:

Substitute it into the second equation:

Divide this equation by 8:

23 school vans and 19 school buses
