QUESTION 2
A donor gives $500 000 to establish a fund to provide an annual prize in perpetuity. Assume the fund will earn ji = 3% p.a. and the prize will be first awarded 2 years after the date of the donation.

c. What is the new amount of the annual prize?

QUESTION 4
At the beginning of 2016 John was planning to set up an education fund for his 4-year-old son Charlie's future HECs fees. Assume that Charlie will go to university in 2030 (14 years later). His HECs fees will be paid at the start of year in 2030, 2031 and 2032 with the predicted amounts being $21500, $23000 and $25000, respectively. Use an interest rate of j4 = 7% p.a. in your calculations.

a. At the beginning of 2030, immediately before Charlie's first HECs payment, what is the present value of Charlie's HECs fees?

At the beginning of 2016 John set up the fund and made a deposit of $3 000 into it. He is planning to make 14 equal annual deposits-the first will be made at the start of 2017-so that the fund can pay Charlie's HECs fees as they fall due.

b. Draw a carefully labelled cash flow diagram that models the above situation. Draw your cash flow diagram from the perspective of the education fund.

c. Determine what John must contribute to the fund over the fourteen years such that it accumulates to an amount sufficient to meet Charlie's HECs fee payments.

QUESTION 5
Jessica has borrowed $1000000 from First Bank for one year. Her under-standing of the terms of the loan is that she will be charged 3% p.a. simple interest in one years' time.
a. What is the total amount (principal and interest) Jessica thinks she needs to repay in one years' time?
Jessica thought the interest rate being charged was 3% p.a. simple interest. It turns out she made a mistake and was, in fact, told by the bank that her interest rate was 3% p.a. compounded half-yearly (i.e., j2 = 3% p.a.).

b. What is the extra amount that Jessica needs for the total repayment at the end of the year?

After some negotiation, First Bank allows Jessica to use 3 equal monthly instalments, paid by at the end of each month, at 5% p.a. compounded half-yearly, to repay the extra amount discussed in b. The first payment will occur one month after the one year term of the loan expires.

c. Draw a carefully labelled cash flow diagram (from Jessica's perspective) to represent the above financial transactions.
