Answer:
Transaction 3 is -155.15
Transaction 4 is -223.75
Step-by-step explanation: for transaction 3 subtract the balance which is 182.35 from previous balance of 337.50, (337.50-182.35=155.15)that gives you the transaction amount of -155.15. Now transaction 4 you have -41.40 so you add that whole negative amount to your previous balance of 182.35, so 182.35+41.40=-223.75.
