This is a fiancial practice question that was given to us. I was wondering if someone could show me how to completely solve this question? for the sake of my understanding is it possible to show calculations that are not on excel or show what the calculator input would be? Thank you

Practice question (Accumulating savings: 20 marks) Mahmoud Hassan will earn $50,000 this year. At the end of this year and subsequent years his salary will increase by 3%. Each year-end he deposits 18% of his salary into an RRSP. After 10 years he will get a promotion and his salary will increase by 20% for the next year, on top of the 3% automatic increase. For 10 years he will continue to get the 3% increase each year. He will still save 18% of his salary each year into an RRSP. He will earn 5% p.a. on the RRSP investments. a) How much will he have in his RRSP after 20 years? b) If the inflation rate is 2% p.a. for every year, what is the real value of that RRSP balance, in today's dollars?
