Jerry intends to use the money from his loan (and his personal savings if necessary) to make an investment in his friend Elaines business. In return, Elaine has predicted the following returns on Jerrys investment:

Four half-yearly payments of $10,000, the first being exactly 6 months from today,

Four half-yearly payments of $20,000, the first being exactly 6 months after the final $10,000 payment described above, and

Two half-yearly payments of $25,000, the first being exactly 6 months after the final $20,000 payment described above

(i.e. there are 10 half-yearly payments in total, the final one occurring exactly 5 years from today). Whilst Elaine is a trusted friend and a capable businesswoman, Jerry has some doubts.

To make a more conservative assessment of the investment, Jerry will expect a higher rate of return. Jerry decides that he requires the following return on his investment: 12% p.a. effective for the first 2 years of the investment, and 15% p.a. compounding quarterly for the remaining term of the investment.

Using this information, answer the following questions. e) For the two rates given above, determine the equivalent effective half-yearly rates. Clearly label your answers. (2 marks)
