To determine which payment method Ishaan can use to purchase the TV that costs $999, we need to evaluate his available funds:
- Cash: $100
- Debit card: $500
- Credit card limit: $300
Now, let's calculate the total available funds:
- Cash: $100
- Debit card: $500
- Credit card: $300
Total available funds = $100 (cash) + $500 (debit) + $300 (credit) = $900
Since the total available funds ($900) are less than the cost of the TV ($999), none of the payment methods can cover the full cost of the TV.
Thus, the correct answer is:
- None of the payment methods is enough to cover the cost of the new TV.
