Final answer:
To find the overdraft balance, the total deposits made by Valeria ($105.06) was subtracted from her final balance ($62.14), resulting in an overdraft balance of -$42.92.
Step-by-step explanation:
The question is asking to find the balance of Valeria's account when it first went into overdraft. We know that she deposited $35.02 each week for 3 weeks and ended up with a balance of $62.14. To find the initial overdraft amount, we need to subtract three times the weekly deposit from the final balance.
Total deposits = $35.02 per week * 3 weeks = $105.06
Initial overdraft balance = Final balance - Total deposits
Initial overdraft balance = $62.14 - $105.06 = -$42.92
Therefore, when Valeria's account went into overdraft, the balance was -$42.92.
