    Calculator = $10.50 Notebook = $2.00 Pen = $1.50 $14.00 - $9.00 = $5.00 $14.00 - $8.50 = $5.50 $5.00 + $5.50 = $10.50 $10.50 - $8.50 = $2.00 $10.50 - $9.00 = $1.50 It can also be solved by a system of 2 linear equations. Though that is much more tedious. I doubt it, but if you want me to post that I will.
