Question

This is the question----New York City is a popular field trip destination. This year the senior class at Franklin High School and the senior class at McKinney High School have both planned trips there. Franklin High rented and filled 1 van and 6 buses for their 324 students. McKinney High rented and filled 9 vans and 3 buses for their 264 students. Every van had the same number of students as did the buses.
A. How many students were in a single van?
B. How many students were in a single bus?

Let x = The number of students in a van.
Let y = The number of students in a bus.

Can someone show me the work on how to do this.

Answer 1

Franklin High: x + 6y = 324       x = 324 - 6y

McKinney High: 9x + 3y = 264

9(324 - 6y) + 3y = 264

2916 - 54y + 3y = 264

-51y = -2652

y = 52

x = 324 - 6(52) = 324 - 312

x = 12
