Answer: The correct answer is $333,333.33
Explanation: Perpetuity is a cashflow that is payable or receivable forever.
In calculating the present value of a Perpetuity, the cash flow will be divided by the rate.
That is $15,000/ 4.5%
=$15,000/ 0.045
=$333,333.33
The money to be set aside now to be able to pay $15,000 every year is $333,333.33
