To determine which situation will result in Kareem having $0 left in his savings account, we need to analyze each option:
A. Kareem spends $123 from his savings account and then deposits $123 in his savings account.
- After spending $123: $123 - $123 = $0
- Then he deposits $123: $0 + $123 = $123
- Final amount: $123
B. Kareem deposits $23 in his savings account and then spends $100 from his savings account.
- After depositing $23: $123 + $23 = $146
- Then he spends $100: $146 - $100 = $46
- Final amount: $46
C. Kareem spends $63 from his savings account and then spends $50 from his savings account.
- After spending $63: $123 - $63 = $60
- Then he spends $50: $60 - $50 = $10
- Final amount: $10
D. Kareem deposits $19 in his savings account and then spends $142 from his savings account.
- After depositing $19: $123 + $19 = $142
- Then he spends $142: $142 - $142 = $0
- Final amount: $0
The option that results in Kareem having $0 left in his savings account is D.
