Final answer:
To get Edna's new bank account balance, add her deposit amount of $286.23 to her current balance of $50.84, resulting in a new balance of $337.07.
Step-by-step explanation:
To find the new balance in Edna's bank account after she deposits her paycheck, we simply need to add the amount of the deposit to her current balance. Edna's current account balance is $50.84, and her paycheck is for $286.23.
The calculation is as follows:

New Account Balance = $50.84 + $286.23
New Account Balance = $337.07
Therefore, the correct answer is A. $337.07.
