Answer:
b)less than $500,000 today, but a positive amount.
Explanation:
By the virtue of the concepts of compounding and discounting, we understand that $1 today is worth more that $1 in the future.
Where Pv = Present value
Fv = Future value
r = discount rate
t = time
Fv = Pv ( 1 + r)^t
As such If a firm can earn a profit stream of $50,000 per year for 10 years, that profit stream is worth less than $500,000 today, but a positive amount.
