Consider the question. Gina has two bank accounts. Each account has a quarter of the balance in Betty's account. If Betty's account balance is $3,456, what is the combined balance of both Gina's accounts?
If the answer is '1728'; explain the reasoning:
Each of Gina's account has $3456 / 4 accounts = $864 / account. Her combined account balance is therefore $864 + $864 = $1728.
