Following is a partially completed performance report for a recent week for direct labor in the binding department of a book publisher. Flexed Budget Original Budget $18, 298 Direct labor Actual $19, 200 Budget Variance The original budget is based on the expectation that 8,260 books would be bound; the standard Is 14 books per hour at a pay rate of $31 per hour. During the week, 8.260 books were actually bound. Employees worked 600 hours at an actual total cost of $19,200. Required: a. Calculate the flexed budget amount against which actual performance should be evaluated and then calculate the budget varlance. (Indicate the effect of each varlance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (I.e., zero varlance).) b. Calculate the direct labor efficiency varlance in terms of hours. (Indicate the effect of each verlence by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (I.e., zero varlance).) c. Calculate the direct labor rate variance. (Do not round Intermediate calculations. Indicate the effect of each varlance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (l.e., zero varlence). Answer is complete but not entirely correct. a. $ 18,290 IS 910 U Flexed budget Budget variance Direct labor efficiency variance Direct labor rate variance b. 18,290 hours U C. S 31 XU
