PART A: Calculate the present worth of ATCF

Part B: perform a sensitivity analysis for each variable (unit price,demand,MARR),Graphically (using a spider plot) investigate the sensitivity of the PW (ATCF) to changes in the above factors.Investigate changes over the interval +- 20%

PART C: To which variable is the project the most sensitive? Explain why and write your comments

PART D: Consider that PW is quite sensitive to changes in unit price. Determine the break-even PW as a function of that variable ,and draw the graph that shows the point of breakeven
