1st equation, each area being 1sq foot and defining
x=area of iridiscent
y=area of red
z=area of blue
1st equation
x+y+z = 6
2nd equation
$45=.75*$6.50*x+.75*$4.50*y+.75*$5.50*z
4.875x + 3.375y + 4.125z = 45
3rd equation from there is to be as much iridiscent glass as red and blue glass combined
x=y+z
x+y+z=0
