Correct Answer: AThe best way to detect the manager's fraud is to compare bad debt expense as a percentage of sales to that of the other outlets. Doing so provides a direct comparison against similar environments, making any abnormalities more visible. If the manager is stealing cash and recording the sales as accounts receivable, and then writing these off as bad debts, this would cause the bad debt expense ratio to be higher in their specific outlet compared to others. Comparing it to previous years wouldn't be as effective because the fraudulent activity might have been occurring for multiple years, making the current year's comparison less revealing.
