Answer:
The development should be not be considered as it not a relevant cash outflow
The $254,000 sale price for existing line is a relevant cash inflow
Cash flows:
Year 0 -$$1,536,000
Years 1-13 $746,000
Explanation:
The development cost has already been incurred,it is not a relevant cash outflow since the cash flows to be considered are those would be incurred in the future in respect of the new line of club heads.
The sale price of the existing line is a relevant inflow as it would only be received as a result of switching to the new line of club heads.
The relevant cash flow from year 1 to 13 is computed thus:
year 0 cash outflow would be the cost of new equipment less the sale price of existing line i.e -$1,790,000+$254,000=-$1,536,000
In years 1 to 13 ,there would cash inflow of $746,000 in each year
