Calculation for what Elroy's incremental profit or loss would be if he chooses option 2 over option 1
Using this formula
Incremental Profit of option 2 over option 1= Profit from option 1 - Profit from option 2
Let plug in the formula
Incremental Profit of option 2 over option 1= ($3,600*3)-(3*$1,100 - $800)
Incremental Profit of option 2 over option 1= $10,800 - $2,500
Incremental Profit of option 2 over option 1= $8,300
Therefore Elroy's incremental profit or loss would be if he chooses option 2 over option 1 would be $8,300
