To motivate her staff, Margaret runs a few different PV scenarios to show how their additional effort could really pay off, Under average conditions, after-tax annual net operating cash flows are $74,000. Under a bit more optimistic (but still possible) conditions. after-tax annual net operating cash flows could be $120,000. She tells her staff that if these higher cash flow amounts could be earned for 4 consecutive years, a portion of that value could be used for employee perks (i.e. celebratory trips paid for by the company). She thinks she has their attention. Using two different possible discount rates ( 6% and 12\%), calculate the range of NPVs for the average and optimistic options. (Round present value factor calculations to 5 decimal places, e.8. 1.25124 and final answers to 2 decimal places e.8. 5,125.36. Enter negative amounts using either a negative sign preceding the number eg. 45 or parentheses es. (45).) Is the difference in these NPV amounts significant enough to suggest some nice perks
