Final answer:
The question is about subtracting Sara's withdrawals from her deposit to verify her ending bank balance. It involves basic arithmetic operations of addition and subtraction.
Step-by-step explanation:
The student is dealing with a practical application of basic arithmetic involving deposits and withdrawals from a bank account. To answer the question, one would calculate the net change in the account balance by adding the deposit to the starting balance and then subtracting the amounts withdrawn. We can demonstrate this with a simple equation: Ending Balance = Starting Balance + Deposits - Withdrawals. Since we know Sara's ending balance is 410 AED and her deposit is 500 AED, we can calculate the total withdrawal by rearranging the equation: Total Withdrawals = Starting Balance + Deposits - Ending Balance
However, if the question is asking us to verify whether the withdrawals and deposit led to the ending balance, we would set up the equation like this: 410 AED (ending balance) = Starting Balance (unknown) + 500 AED (deposit) - (120 AED + 60.25 AED + 39.75 AED) (withdrawals). When we subtract 500 AED and add the sum of the withdrawals from both sides of the equation, we can solve for the starting balance.
