4) The best estimates for two investment opportunities are as follows: Alternative 1 Alternative 2 Initial investment (please see the table for your value) $34,000 $25,000 Net annual return Salvage value Estimated life MARR $22,000 8 years 12% $5,000 4 years 12% a) Show the sensitivity of the annual equivalentworth of the cash flow to MARR by plotting AE (y-axis) against MARR of 8%, 10%, 12%, and 14% (x-axis). Decide which alternative is more desirable. b) If MARR is 12%, show the sensitivity of the annual equivalent worth of the cash flow to estimated life values by plotting AE (y-axis) against estimated life of 4, 8, 12 years (x-axis). Decide which alternative is more desirable. Assume the salvage values and annual operating costs are the same for each life value. c) Compute the break-even value of MARR for two investments
