Answer:
1. 1.875 hours
2. $20.25
3. $37.97
Explanation:
The computation is shown below:
1. For Standard direct labor hours per oil change, it is
= (Actual time spent on the oil change) + (Setup and downtime + Cleanup and rest periods) × Actual time spent on the oil change
= 1.25 hours + (22% + 28%) × 1.25 hours
= 1.25 hours + 0.625 hours
= 1.875 hours
2. Standard direct labor hourly rate, it is
= (Hourly wage rate) + (Payroll taxes + Fringe Benefits) × hourly wage rate
= $15 + (10% + 25%) × $15
= $15 + $5.25
= $20.25
3. And, the standard direct labor cost per change is
= Standard direct labor hours per oil change × Standard direct labor hourly rate
= 1.875 hours × $20.25
= $37.97
We simply applied the above formulas for each one part
