1. [10] Suppose you would like to accumulate $1,000,000 by the time you retire in 40 years. Assuming that you are earning 10% on your investments (for the 40 years), how much should you invest every month in order to realize your goal. Investment per year=1,000,000 (A/F,10%.40)=2259.4 Investment per month=2259.4/12=188.28 2. [10] Consider the sequence of cash flows given in the table. Convert the sequence to an equivalent uniform sequence over N = 7 periods. The interest rate is i = 10% per period. End of period 1 2 3 4 5 6 7 Cash flow $300 340 380 420 460 500 540 We decompose the cash flow into 2 cash flows:{300,300,300,…} and {0,40,80,120,…} Annual equivalent of the first cash flow A 1 =300. Annual equivalent of the second cash flow A 2 =40(A/G,10%,7)=104.864. Annual equivalent of the original cash flow=A 1 +A 2 =404.864. 3.
