Question: Alley entered into the work force in 2017. Alley turned 19 on December 10, 2018 and with the money that she received from her grandparents, she maximized her first Registered Retirement Savings Plan (RRSP) contribution the day after her birthday. Her RRSP contribution will result in a tax saving of $1,200 when she files her 2018 personal income tax return.

a)Alley is in the lowest combined marginal tax bracket (See Table A). What was the amount of Alley's RRSP contribution in 2018?

b) What was Alley's salary in 2017?

So I've found that her RRSP contribution was $4358.88 but they ask me to find her salary in 2017. I feel like I don't have enough information to find that out. I thought I could do : gross salary= lowest income bracket ($43,055 + contribution to RRSP ($4,358.88) = $47,413.88

so I've said that alley's salary was between 0 and $ 47,413.88.

I'm pretty sure im wrong so if you could help me out on that one i would appreciate it.

Thank you

Jeremy
