A three-week look-ahead shows 320, 400, and 360 labor-hours. What is the average weekly labor-hours?
Correct Answer
C) 360 labor-hours
Total labor-hours =320+400+360=1080. Divide by 3 weeks to obtain an average of 360 labor-hours per week. Reporting 1080 gives the three-week total; converting to worker headcount would require an assumed workweek per worker.
Why This Is the Correct Answer
Total labor-hours =320+400+360=1080. Divide by 3 weeks to obtain an average of 360 labor-hours per week. Reporting 1080 gives the three-week total; converting to worker headcount would require an assumed workweek per worker.
