B

Step-by-step explanation:

Starting balance is $557.83.

Deposited checks adds to the beginning balance

557.83 + 882.84 = 1440.67

Cash withdraw subtracts from the new balance

1440.67 - 325 = 1115.67

Checks paid by the bank subtract from the new balance

1115.67 - 617.77 = 497.90

Interest gets added onto the new balance

497.90 + 1.15 = 499.05
