Final answer:
To find the new balance, add the current balance to the amount charged. In this case, the new balance is $333.
Step-by-step explanation:
To find the new balance, we need to add the amount charged to the current balance. Since Emily owes $264 on her credit card and charges $69 more, we can add these two amounts together:
$264 + $69 = $333
Therefore, the new balance is $333.
