The answer to your question is 18 withdrawals.
The interest for you get from local back will be $ 2000 (2.2%) = $ 44 .
The interest for you get from online savings account will be $ 2000 (4.85%) = $ 97 .
So $ 97 - $ 3(x)=44 ; x = number of withdrawals
Solve for x
x = 17.66666
x = 18 withdrawals
Hope my answer would be a great help for you.
