Junior Class
120 turkey dinner plates
200 chicken dinner plates
total of $2,150.
....
the senior class
100 turkey plates
300 chicken dinner plates
total of $2,625.
..
Let turkey dinner plate cost $x
Chicken dinner plates cost $y
...
Junior ---120x+200y = 2150..................1
Senior ----100x+300y = 2625.................2
multiply (1) by -3 & (2) by 2
-360x-600y=-6450
200x+600y = 5250
..
Add both equations
-160x= -1200
/-160
x= -1200/-160
x=7.50
$ 7.50 for Turkey dinner plate
