On Monday a computer manufacturing company sent out 3 shipments.
First Order is for $114,000
4 model II, 6 model VI, 10 model IX computers
Second Order is for $72,000
8 model II, 3 model VI, 5 model IX
Third order is for $81,000
2 model II, 9 model VI, 5 model IX

What does the manufacturer charge for a Model VI computer?

Set up a system of equations.

Let x=price of Model II
Let y=price of Model VI
Let z=price of Model IX

4x+6y+10z=114,000
8x+3y+5z=72,000
2x+9y+5z=81,000

Solve the system. When you find the value of y, that is the price of the Model VI.
