Final answer:
To receive a perpetual cash flow of $15,000 every year at an interest rate of 9 percent annually, Stuart Weddle's father would need to invest approximately $166,667 today.
Step-by-step explanation:
To calculate the present value of a perpetual cash flow, we can use the formula:
Present Value = Cash Flow / Interest Rate
In this case, Stuart Weddle's father wants to receive $15,000 every year, beginning at the end of this year. The interest rate is 9 percent annually.
So, the present value can be calculated as follows:
Present Value = $15,000 / 0.09
Rounded to the nearest dollar, the father would need to invest approximately $166,667 today to receive his perpetual cash flow.
