Answer:
the NPV of drilling in two more years is $74,430 higher in current dollars than drilling today
Step-by-step explanation:
we can assume that these are 2 different projects:
project A:
initial outlay -$925,000
CF 1 $600,000
CF 2 $600,000
CF 3 $600,000
CF 4 $600,000
discount rate = 17.5%
NPV = -$925,000 + $600,000/1.175 + $600,000/1.175² + $600,000/1.175³ + $600,000/1.175⁴ = $704,859
project B (in two years):
initial outlay -$975,000
CF 1 = ($1,000,000 x 65%) + ($300,000 x 35%) = $755,000
CF 2 = $755,000
CF 3 = $755,000
CF 4 = $755,000
discount rate = 17.5%
NPV = -$975,000 + $755,000/1.175 + $755,000/1.175² + $755,000/1.175³ + $755,000/1.175⁴ = $1,075,906 in two years
now we need to discount the NPV ⇒ $1,075,906/1.175² = $779,289
the NPV of drilling in two more years is $74,430 higher in current dollars than drilling today = $779,289 - $704,859 = $74,430
