Your subscription to Financial Times is about to expire. You plan to subscribe to the news paper for the rest of your life, and you can renew it by paying $60annually, beginning immediately, or you can get a lifetime subscription for $700, also payable immediately. If you can earn 4.0% on your funds and that the annual renewal rate will remain constant, how many years must you live to make the lifetime subscription the better buy?
