Part 1:
The account will be -14.57 after two days.
Step by step:
What I do is just forget the negatives until the end.
5.95 + 5.95 (two days) + 2.67 = 14.57
Bring back the negative: -14.57
Part 2:
Lin's sister will have more than $0 in the account, so she won't be charged after this deposit is made.
