This problem demonstrates the dependence of an annuity's future value on the size of the periodic payment. Suppose a fixed amount will be invested at the end of each year and thal the invested funds will earn 4.8% compounded annually. What will be the future value of the investments after 20 years if the periodic Investment is: (Do nor round intermediate calculations and round your final answers to 2 decimal places.) Fuhure Value $ Investment $1,500 per year 7,000 per year $3,888 per year $ $ An endowment fund is set up with a donation of $170,000. If it earns 5.8% compounded monthly, for how long will it sustain end-of- month withdrawals of $1,700? (Include the final smaller withdrawal.) (Do not round intermediate calculations and round up the number of payments, n, to the next whole number.) Endowment is for year(s) and month(s)
