H 2.1 = Ahmed is 48 years old now. He is planning to retire in 12 years. He can deposit money for his retirement at 8% compounded quarterly. Ahmed estimates that an amount of $30,000 + X per year in terms of today's dollars (dollars at Ahmed's age of 48 years), will be required to support his retirement income for four years. The retirement incomes are estimated to increase at an annual rate of 6% Determine the equal quarterly deposits that Ahmed must make until his retirement. Assume that the first deposit will be made at the end of the first quarter and that deposits will continue until Ahmed reaches age 60.
