The interest rate on the loan is E% per annum (effective). The interest must he paid every 2 months, with the interest payment equal to the interest earned on the loan over the previous 2 month period. The project earns $Y at the end of each month, for 10 years. The reinvestment rate on earnings from the project =_,r'% per annurn (effective).
