On average, Guillermo has found that a typical oil change takes 24 minutes and 6.2 quarts of oil are used. In June, Guillermo's Oil and Lube had 970 oil changes. Guillermo's Oil and Lube Company provided the following information for the production of oil changes during the month of June: Actual number of oil changes performed: 970 Actual number of direct labor hours worked: 382 hours Actual rate paid per direct labor hour: $14.50 Standard rate per direct labor hour: $14.00 Required: If required, round your answers to the nearest cent. 1. Calculate the direct labor rate variance (LRV) and the direct labor efficiency variance (LEV) for June using the formula approach. 2. Calculate the total direct labor variance for oil changes for June. 3. What if the actual wage rate paid in June was $13.50 ? What impact would that have had on the direct labor rate variance (LRV)? On the direct labor efficiency variance (LEV)? Indicate what the new variances would be below. Direct labor rate variance (LRV): $ Direct labor efficiency variance (LEV): 5
