II. Thursday

III. Friday

Step-by-step explanation:

Each time Anna makes a withdrawal from her account with the bank, the account is debited and when she makes a deposit, the account is credited to the tune of the amount deposited. As such, a debit is a negative transaction  and a credit is positive.

On Monday, there was a debit ($) 194.62 and a credit ($) 35.45

Closing balance on Monday, considering the opening balance which is the closing balance from Sunday

= $ 274 - $ 194.62 + $ 35.45

= $ 114.83

Anna's bank balance is Positive at the end of Monday, hence no overdraft fee will be charged by the bank.

On Tuesday, there was a debit ($) 0 and a credit ($) 11.20

Closing balance on Tuesday, considering the opening balance which is the closing balance from Monday

= $ 114.83 - $ 0 + $ 11.20

= $ 126.03

Anna's bank balance is Positive at the end of Tuesday, hence no overdraft fee will be charged by the bank.

On Wednesday, there was a debit ($) 145.86  and a credit ($) 24.75

Closing balance on Wednesday, considering the opening balance which is the closing balance from Tuesday

= $ 126.03 - $ 145.86 + $ 24.75

= $ 4.93

Anna's bank balance is Positive at the end of Wednesday, hence no overdraft fee will be charged by the bank.

On Thursday, there was a debit ($) 53.35  and a credit ($) 33.80

Closing balance on Thursday, considering the opening balance which is the closing balance from Wednesday

= $ 4.93 - $ 53.35 + $ 33.80

= - $ 14.62

Anna's bank balance is Negative at the end of Thursday, hence she gets charged an overdraft fee by the bank.

On Friday, there was a debit ($) 31.60  and a credit ($)  45.77

Closing balance on Friday, considering the opening balance which is the closing balance from Thursday

= - $ 14.62 - $ 31.60 + $ 45.77

= - $ 0.45

Anna's bank balance is Negative at the end of Friday, hence she gets charged an overdraft fee by the bank.

As such Anna's closing accounts balances were - $ 14.62 and - $ 0.45 on Thursday and Friday respectively. As such, she will be charged an overdraft fee for these two days.
