The screenshot below is from a template solution for a problem. Assume that all values under 'Input Parameters' are constant and would not change. Values under 'Decision Variables' are decision variables and can be changed.

You can download the excel file by clicking

$\backslash$table$[[A,$A$,$B$,$C$,D^{},E,$F$],[1,$Input Parameters$],[2,3,1$:$,$Product $1,$Product $2,$Product $3,],[3,,$Unit Profit,$$48,$$$55,$$$50,],[4,,$Fixed$-$Cost,$$1,000,$$$800,$$$900,],[5,$Minimum,Production Amt.,$30,,,],[6,,,$Hours Required,$],[7,,$Resources,Product $1,$Product $2,$Product $3,$Available$],[8,,$Machining,$-2,3,6,600],[9,,$Grinding,$6,3,4,300],[10,,$Assembly,$5,6,2,400],[11],[12,$Decision Variables,,,,,$],[13,,,$Product $1,$Product $2,$Product $3,],[14,$Are we producing?,,,,A$],[15,$Amount of production,,,,i$.],[16,,,,],[17,$Objective,,,,$],[18,$Total profit bef,ore the setup cost,,,,$],[19,,$Setup Cost,,,,$],[20,,$Total Profit,,,,$]]$

For the following formula, will the result be linear, non$-$linear, or cannot be determined?

$=C{3}^{**}C15+D{3}^{**}D15+E{3}^{**}E15$

Linear

Non$-$Linear
