Calculate labour rate and efficiency variances.
【参考答案及解析】
Labour rate variance Take the number of labour hours worked and paid for, and compare the actual amount paid with the standard rate for the hours worked. $ 4,200 hours should have cost (× $6) 25,200 but did cost 24,150 Rate variance (actual cost less than the standard rate) 1,050 (F) Labour efficiency variance Take the actual quantity of units produced and compare the actual time to produce them with the standard time. The variance is converted into a monetary value at the standard rate per labour hour. 800 units should have taken (× five hrs) 4,000 hrs but did take 4,200 hrs Efficiency variance in hours (actual time longer than standard) 200 (A) × standard rate per hour × $6 Efficiency variance in $ $1,200 (A)
