Sensitivity analysis: San Lucas Corporation San Lucas Corporation is considering investment in robotic machinery based upon the following estimates: Cost of robotic machinery $4,000,000 300,000 Residual value Useful life 10 years a. Determine the net present value of the equipment, assuming a desired rate of return of 10% and annual net cash flows of $700,000. Use the present value tables appearing in Exhibit 2 and 5 of this chapter. Net present value $ 417,300 b. Determine the net present value of the equipment, assuming a desired rate of return of 10% and annual net cash flows of $500,000, $700,000, and $900,000. Use the present value tables (Exhibit 2 and 5) provided in the chapter in determining your answer. If required, use the minus sign to indicate a negative net present value. Annual Net Cash Flow $500,000 $700,000 $900,000 Net present value $ c. Determine the minimum annual net cash flow necessary to generate a positive net present value, assuming a desired rate of return of 10%. Round to the nearest dollar. Annual Net Cash Flow $
