dexar [7]

Answer:

By December, her account balance is

$468.98

Step-by-step explanation:

Jimmy's savings account balance was $76.23 in june. By September, her balance is five times as much as her June balance. This means that by September, her balance is

5 × 76.23 = $381.15

Between September and December, she made a deposit of a total of $87.83 into her account.

This means that her new account balance is 381.15 + 87.83

= $468.98

If she does not withdraw any money from her account, her account balance will remain the same by December. This means that by December, her account balance is

$468.98
