An engineer is choosing between three different alternatives for a machine component he needs to complete his biorefinery. He summarized the pertinent information about these alternatives in the tables below. Assume a study period of $8$ years

$\backslash$table$[[$Alternative$,$Investment Cost,Salvage Value,Useful Life,Depreciation Method$],[$A$,100,000,25,000,8,$Sum of the Years$],[$B$,70,000,20,000,4,$Straight Line$],[$C$,76,000,5,000,6,$Declining Balance$]]$

The table below shows the projected net cash flows for each of the alternatives.
