For the past four years, Darren has been saving up for a college fund for his oldest daughter. He deposited $5,000 initially, followed by annual deposits of $5,000, $4,000, $3,600, and $5,000. The money was initially invested at 5.75% compounded semi-annually for the first two years before increasing to 6% compounded quarterly for the balance of the investment.
