Thank you for your question, Kinley!
To solve this one you want to use the formula
Ending Balance = Starting Balance + Deposits – Withdrawals
Using the values given in the question that would be
Ending Balance = 85 + 32 + 115 + 45.18 + 59.65 – 49.15
Ending Balance = $287.68
That means that the correct answer here would be choice (b)
