Answer:
transaction 3 (account balance) = 143
transaction 4 (account balance) = -86
transaction 5 (transaction amount) = 86
Step-by-step explanation:
From the table it is seen that after transactions the account balance either increases or decreases.
Transaction 1
transaction amount was 200 while account balance became 200
Transaction 2
the initial startup balance will be = transaction amount + current account balance which is = 147 + 53 = 200 .
Note: the account balance of the previous transaction becomes the initial account balance of the next transaction
Transaction 3
account balance = initial account balance + transaction amount
= 53 + 90 = 143
Transaction 4
account balance = initial account balance + transaction amount
= 143 + ( - 229 ) = - 86
Transaction 5
transaction amount = account balance - initial account balance
= 0 - ( -86 ) = 86
