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 Actual Budget Variance Direct labor $ 11,000 $ 10,710 The original budget is based on the expectation that 6,000 books would be bound; the standard is 12 books per hour at a pay rate of $22 per hour. During the week, 6,240 books were actually bound. Employees worked 510 hours at an actual total cost of $10,710. Required: Calculate the flexed budget amount against which actual performance should be evaluated and then calculate the budget variance. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance).) Calculate the direct labor efficiency variance in terms of hours. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance).) Calculate the direct labor rate variance. (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)
