Also a $5,000 expense came at the end of the fourth year. Office starts at the end of the 5th year. 4% interest per year (compounding annually), draw the cash flow diagram for the 5 years assuming he wants to withdraw funds at the end of the year. Also, find the future value of investments at the end of the 5th year
