1 Matt recently deposited $30,000 in a savings account paying a guaranteed interest rate of 4 percent for the next 10 years. If Matt expects his marginal tax rate to be 22 percent for the next 10 years, how much interest will he eam after-tax after the seventh year of his investment if he withdraws enough cash every year to pay the tax on the interest he eams?
