Answer:
Given:
Allowance for Doubtful Accounts is a credit of $760
Written off accounts = $120
Accounts totaling = $740
The end-of-year balance (before adjustment) in Allowance for Doubtful Accounts will be computed as:
Allowance for Doubtful Accounts - Accounts totaling + Written off accounts
⇒ $760 - $740 + $120
⇒ $140
therefore, the correct option is (c).
