Question 531023
A Senior class is planning a trip to Chicago.
---------------------------------- 
A bus seats 51 people ; a van seats 8 people. If there are 150 students going on the trip in a total of 8 vehicles, how many buses and vans are taken on the trip?
---------
b   +  v = 8   vehicles
51b + 8v = 150 students
----
Multiply thru the 1st equation by 8 to get:
8b  + 8v  = 64
51b + 8v = 150
-----
Subtract and solve for "b":
43b = 86
b = 2 (# of busses)
-----
Solve for "v":
b + v = 8
2 + v = 8
v = 6 (# of vans)
