Person A opens an IRA at age 25, contributes $2000 per year for 10 years, but makes no additional contributes thereafter. Person B waits untill age 35 to open an IRA and contributes $2000 per year for 30 years. There is no initial investment in either case. Asumming an interest rate of 8%, what is the alance i each IRA at age 65?
