What calculation is performed to derive gross pay for overtime work?

The calculation that derives gross pay for overtime work primarily involves taking the standard hourly rate and multiplying it by the regular hours worked. For hours worked beyond the standard regular hours, employees are entitled to receive an overtime rate, which is typically 1.5 times their standard hourly rate. Therefore, when calculating gross pay, the total is obtained by adding the pay for the regular hours to the pay derived from the overtime hours.

In this case, the correct choice reflects this comprehensive calculation. It encapsulates both components needed to determine gross pay: the standard pay for regular hours and the additional pay for any overtime worked, factoring in the elevated overtime rate for those extra hours. This ensures that employees are fairly compensated for time worked beyond the normal workweek.

Other options do not fully capture the complexity of overtime calculation. Some may restrict the calculation to only regular hours worked, disregard the necessity of calculating overtime, or fail to address how overtime pay interacts with the regular pay structure. This illustrates the importance of understanding both the basic pay calculation and the required adjustments for overtime work, especially in a business context.
