How do you determine the number of actual labor hours spent opening batches during the week when 168 batches were received and the standard hours is 1.25 standard rate 12 and the standard cost 15?

To determine the actual labor hours spent opening batches, you first multiply the number of batches received (168) by the standard hours per batch (1.25). This gives you a total of 210 actual labor hours (168 batches * 1.25 hours/batch). The standard rate and standard cost are not needed for this calculation, as they pertain to cost analysis rather than the determination of labor hours. Thus, the total labor hours for the week is 210 hours.
