Decision #2: Planning forRetirement

Erich and Mallory are 22, newly married, and ready to embark onthe journey of life.   They both plan to retire 45 yearsfrom today. Because their budget seems tight right now, they hadbeen thinking that they would wait at least 10 years and then startinvesting $3000 per year to prepare for retirement. Mallory justtold Erich, though, that she had heard that they would actuallyhave more money the day they retire if they put $3000 per year awayfor the next 10 years - and then simply let that money sit for thenext 35 years without any additional payments – then they wouldhave MORE when they retired than if they waited 10 years to startinvesting for retirement and then made yearly payments for 35 years(as they originally planned to do).   Please helpErich and Mallory make an informeddecision:   

Assume that all payments are made at the END a year(or month), and that the rate of return on all yearly investmentswill be 7.2% annually.
