Answer:
The one time fee that the owner should charge is $1764.71
Explanation:
To calculate the one time fee, we take this as a perpetuity and calculate the value or price of the perpetuity based on the fututre cash flows discounted to today's price by a certain dicount rate.
The discount rate is taken as 8.5% which is also the market interests rate.
The formula for the value/price of the perpetuity is,
Value / Price = Cash flow / Discount rate
Value / Price = 150 / 0.085
Value / Price = $1764.705 rounded off to $1764.71
