Assuming that ' i ' is the old familiar square root of -1 ...
The square of 6i is -36 .
Of course, if ' i ' is something else, then (6i)² = 36 i² .
Let's assume
amount invested is P
Since, we are given
Nolan invested equation as
Anias invested equation as
now, we can set them equal
now, we can solve for P
now, we can simplify it
So, she needed to invest $94.2322 to have the same amount of money that she has three years later........Answer
