Question 1012599
.01x+.10y+.50 z=5.00
x+y+z=100
x has to be a multiple of 10
y is less than 47
z is less than or equal to 9
x+10y+50z=500
If z=9, y and x can't add to 100 and equal 0.50
z=8, 
x+y=92
x+10y=100
-x-y=-92
9y=8, non-integer.
==============
z=1
x+y=99
x+10y=450
-x-y=-99
9y=351
y=39=$3.90
x=60=$0.60
z=1=0.50
$5.00
