Mira has opened a registered retirement income fund (RRIF) with a starting balance of $250,000. Beginning 6 months later, she plans to make semi-annual withdrawals from the RRIF for 20 years. The withdrawals will increase at a constant rate of 1.75%. If the RRIF earns 8% compounded semi-annually, how much is the amount of interest included in the total withdrawals? I am studying for an exam so I need a step by step answer as I'm not getting the answer provided of $302,131.40. Thanks for your help
