The correct balance = $21.46
Step-by-step explanation:
Earnings 1st week = $25.67
Earnings 2nd week = $37.85
Total earnings = $25.67 + $37.85
Total earnings = $63.52
Expenses:
DVD purchase = $19.99
Gas purchase = $22.07
Total purchase = $19.99 + $22.07 = $42.06
Balance in the checking account = 0
Balance from Justin's earnings = Balance in the checking account + Total earnings - Total purchase
= 0 + $63.52 - $42.06
Balance from Justin's earnings = $21.46
According to the question, we are told the balance is $105.58. This is wrong because we are told he started with a zero balance and from our calculation, the balance that is meant to be found in the account is $21.46
The correct balance = $21.46
