Employee regular earnings are calculated based on which of the following formulas?

Employee regular earnings are determined by multiplying the number of regular hours worked by the regular hourly rate. This method accurately reflects the compensation for the standard hours an employee is expected to work without any additional factors such as overtime or commissions.

Understanding this formula is crucial because it forms the basis of payroll calculations for employees who are compensated on an hourly basis. Other choices involve different contexts of earnings—like overtime calculations, commissions based on sales, or division by hours worked for salaried employees—which are not applicable to the calculation of regular earnings specifically. Thus, the formula involving regular hours and the regular rate is essential for correctly determining the wages earned during regular work hours.
