Accounting What the Numbers Mean 9e Demonstration Problem Chapter 15 – Exercise 5 Direct Labor Variances – Solving for Unknowns

2 Problem Definition Ackerman’s Garage uses standards to plan and control labor time and expense. The standard time for an engine tune-up is 3 hours, and the standard labor rate is $25 per hour. Last week, 42 tune-ups were completed. The labor efficiency variance was 14 hours unfavorable, and the labor rate variance totaled $140 favorable.

3 Problem Requirements Calculate the actual direct labor hourly rate paid for tune-up work last week. Calculate the dollar amount of the labor efficiency variance. What is the most likely explanation for these two variances? Is this a good trade-off for the management of the garage to make? Explain your answer.

34 Problem Solution Less skilled, lower paid workers took longer than standard to get the work done. The net variance is $210U ($350U - $140F). This was not a good trade-off based on the variance. From a qualitative viewpoint, less skilled workers may not do as good of a job.
