Answer:
a. Select the time line that represents the cash flows involved in the offer.
NCF1 = $28,000
NCF2 = $23,000
NCF3 = $15,000
NCF4 = $15,000
NCF5 = $15,000
NCF6 = $15,000
NCF7 = $15,000
NCF8 = $15,000
NCF9 = $15,000
NCF10 = $30,000
If you want to compare this set of cash flows to another offer, you will need to calculate the present value first. E.g if you use a 12% discount rate, the PV of these cash flows = $107,570.
