Which statement is true regarding the input in wages systems of payroll?

In payroll systems, the inputs that are crucial for calculating employee wages typically include both clock cards and bonuses. Clock cards serve as a record of the hours worked by employees, which is essential for determining total pay based on hourly wages. The amount of bonus is equally important, as it represents an additional compensation that is often linked to performance or other criteria.

Therefore, the notion that clock cards and the bonus amount are the main inputs reflects the reality that accurate payroll processing relies on both the tracking of time worked and the inclusion of various forms of employee compensation, such as bonuses. This ensures that employees are paid correctly according to their worked hours and any additional earnings, promoting a fair and transparent payroll process.

In contrast, the other statements incorrectly suggest that elements like clock cards and bonuses are irrelevant or not required, which does not align with standard payroll practices where these elements play a critical role in accurate wage calculation.
