Answer:
The value of the option to wait is $0.70,option A.
Explanation:
In calculating the value of the option to wait,I discounted all cash flows under both alternatives, using the discount rate of 12% as given in the question.
Option to start now gives net present value(positive return ) of $360.64 while the other one gives $361.34,invariably option to wait one year gives $0.70($361.34-$360.64) more than the option to start now.
The formula used in the calculating present value is PV=FV(1+r)^n
Where PV=present value
FV=future value
r=rate of interest
n=number of year
