Final answer:
The net realizable value of the accounts receivable on the December 31, 2011 balance sheet would be $59,550.
Step-by-step explanation:
To calculate the net realizable value of accounts receivable, we need to determine the allowance for doubtful accounts. In this case, Hailey Medical Co. estimates that it will be unable to collect 6% of revenue on account, which amounts to $4,950 ($82,500 * 6%). Therefore, the net realizable value of accounts receivable on the December 31, 2011 balance sheet would be $59,550 ($64,500 - $4,950).
