Answer:
C.$72,867
Step-by-step explanation:
The present value = Future value/(1+rate)^n, in which n is number of period
So value of $50,000 at employment date = $50,000/(1+8%)^2 = $42,867
So the lump sum at employment date = $30,000 + $42,867 = $72,867
And this amount ($72,867) is indifferent with $30,000 at the date of employment and another $50,000two years later.
