An investor invests $53,030.00 and receives an annuity of
$7,000.00 at the end of each year for 12 years and an additional
payment of $15,000.00 at the end of the 13th year. Each time he
gets a $7,000.00 payment, he immediately deposits $4,000.00 in a
savings account that earns 9%. Find the annual yield received by
the investor over the 13 year period.
Please provide a mathematical explanation to the answer if
possible. I am more concerned with semantics.
