Following is a partially completed performance report for a recent week for direct labor in the binding department of a book publisher: Original Budget Flexed Budget $ 15,680 Direct labor Actual $ 16,530 Budget Variance The original budget is based on the expectation that 10,080 books would be bound; the standard is 18 books per hour at a pay rate of $28 per hour. During the week, 10,800 books were actually bound. Employees worked 570 hours at an actual total cost of $16,530. Required: a. Calculate the flexed budget amount against which actual performance should be evaluated and then calculate the budget variance. b. Calculate the direct labor efficiency variance in terms of hours. c. Calculate the direct labor rate variance. Note: Do not round intermediate calculations. Note: For all requirements, indicate the effect of each variance by selecting "F" for favorable. "U" for unfavorable, and "None" for no effect (i.e., zero variance). a. Flexed budget a Budget variance b. Direct labor efficiency variance c. Direct labor rate variance hours Smallman's Garage uses standards to plan and control labor time and expense. The standard time for an engine tune-up is 3.75 hours, and the standard labor rate is $15 per hour. Last week, 26 tune-ups were completed. The labor efficiency variance was 15 hours unfavorable, and the labor rate variance totaled $80 favorable. Required: a. Calculate the actual direct labor hourly rate paid for tune-up work last week. Note: Do not round intermediate calculations. Round your answer to 2 decimal places. b. Calculate the dollar amount of the labor efficiency variance. Note: Do not round intermediate calculations. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). c. Less skilled, lower paid workers took longer than standard to get the work done is the most likely explanation for these two varlances. a. Actual direct labor rate per hour b. Direct labor efficiency variance c Less skilled, lower paid workers took longer than standard to get the work done is the most likely explanation for these two variances
