Mantekilla Mantilla plans to make a series of deposits in an individual retirement account. You will deposit $2,500 today, $2,800 in two years, and $3,500 in five years. If you withdraw $1,500 in three years, $1,000 in seven years, and $ 1200 in nine years, assuming no withdrawal penalties, how much will you have after twelve years if the interest rate is 7.5 percent?
