Answer:
Lump sum payment today =$6,659,388.81
Step-by-step explanation:
The lump sum payment that would make her indifferent is the present value of the annuity discounted at the required rate of return of 5%.
PV = A × (1 - ((1+r)^(-n))/n)
A- $450,000, r- 5%, n = 25-1 = 24
Because , the first payment occurs today, we wil take the number of payment to be 24 (i.e 25 - 1) . And then add the first payment to the Present value the of the 24 year annuity.
This is so because the first payment need not be discounted because it is already in present value.
PV = $450,000 × 1- (1.05)^(-24)/0.05
= 6,209,388.81
Total Present value = $450,000 + 6,209,388.81
= $6,659,388.81
