For part B, you need the rational numbers from part A. you use the rational numbers and you order them from least to greatest. Once you finish ordering them least to greatest, you need to explain your reasoning (behind why you did the ordering the way you did).
For part C, you add all of his deposits to his balance. Then you add the withdrawls together and then you subtract the withdrawl total from the total amount in his account.
If these answers are incorrect, then I am sorry.
