Your current balance if you started the day with $100 in your account is $73
First step is to calculate the total cash at bank
Using this formula
Total Cash at bank= Cash at bank + Deposit
Let plug in the formula
Total Cash at bank=$100+90
Total Cash at bank=$190
Second step is to calculate the amount debited
Debit amount=($60+$3)+($34+$20)
Debit amount=$63+$54
Debit amount=$117
Now let determine your current balance
Current balance=Total cash at bank-Amount debited
Let plug in the formula
Current balance=$190-117
Current balance=$73
Your current balance if you started the day with $100 in your account is $73
