Donald is the owner of a small restaurant, and is considering renovating his kitchen and buying new equipment to keep up with increasing business. He has received a quote of $30,000 from the contractor John for this renovation and equipment. After some additional research and negotiation, Donald has noted/secured the following:

• John has agreed to let Donald pay the $30,000 cost of the renovation as 10 equal fortnightly payments (i.e. 10 payments of $3000), the first being made immediately.
• The final repayment will coincide with the completion of the renovation. Donald can reopen his restaurant immediately after this.
• Donald's bank account pays interest at 6.7% p.a. compounding semi-annually.

For the purposes of this question, assume he can both invest and borrow at this rate.

(a) Determine the equivalent effective annual rate for Donald's account. (1 mark)

Donald decides to call up his bank to renegotiate the interest rate. After discussing his situation, the bank has agreed to lend money to Donald for this renovation at an effective fortnightly rate of 0.1064%. Using this new interest rate, determine the following:

b) As noted earlier, the $30,000 cost of the renovation can be spread out as 10 equal fortnightly payments, the first being made immediately. Using the new interest rate, determine the present value of these 10 repayments.
