2. Grace, age 55, wants to retire at age 65. Her financial goal is to have $500,000 in her registered retirement savings plan (RRSP) by that time. She has $250,000 saved in her RRSP so far and is concerned she won’t be able to reach her goal; her RRSP monies earn 4% annually. If Grace were to make a one-time investment today in order to reach her retirement savings goal, how much money will she need to invest?
