Roper Spring Water should not buy the machine, since it produces a negative net present.
Explanation:
Summary of Cash Flows on the Machine are as follows :
Year 0 = ($230,000)
Year 1 = $55,000
Year 2 = $65,000
Year 3 = $75,000
Year 4 = $75,000
Interest rate = 7%
Using the CFj Function of the Financial calculator this will be computed as :
($230,000) CF j 0
$55,000 CF j 1
$65,000 CF j 2
$75,000 CF j 3
$75,000 CF j 4
i/yr = 7%
Therefore Net Present Value is - $3,385.13
Since this is a negative Net Present Value, Roper Spring Water should not buy the machine.
