2. Today is 1 July 2019. John needs $160,000 on 1 January 2024. He plans to invest $80,000 into a fund today. John predicts that the return rate of this fund will be 1 July 2019 to 30 June 2021 j2 = 5.1% 1 July 2021 to 31 December 2023 12 = 5.3% a. Calculate the accumulated value of John's fund investment on 1 January 2024 (round your answer to four decimal places.). b. To save for remaining required amount on 1 January 2024 (the difference between the $160,000 and the accumulated value from part a), John plans to deposit z% of his annual after-tax salary into a saving account on 1 July of each year from 2019 to 2023 (5 deposits in total). The saving account rates are assumed to be 0.2% per month. Assume that John's after-tax salary is $90,000 p.a. Find the value of 2 (expressed as a percentage and rounded to two decimal places). c. From John's perspective, draw a carefully labelled cash flow diagram to rep- resent the above financial transactions of parts c and d
