b. Consider the scenario where Darcy decides to postpone making his RRSP contributions until he turns 35, but then he doubles his monthly contribution amount to $250. He is able to invest into the same type of RRSP until retirement at 50. What is the amount in his RRSP on his 50th birthday? What is the better option for him? How much more money did the better option make for Darcy? (6 marks)
