---------------------
Equation:
f + e <= 10 boxes
15f+18e <= 90 dollars
--------------------------------
Modify for graphing:
f <= -e + 10
f <= (-6/5)e + 6
--------

======================
One solution: 2 boxes of 5 ounce and 3 boxes of 8 ounce
2nd solution: 2 boxes of 5 counce and 2 boxes of 8 ounce
