Exercise 10-5 Working Backwards from Labor Variances [LO10-2] The auto repair shop of Quality Motor Company uses standards to control the labor time and labor cost in the shop. The standard labor cost for a motor tune-up is given below: StandardStandard RateStandard Cost Hours 1.58 Motor tune-up $6.20 $9.30 The record showing the time spent in the shop last week on motor tune-ups has been misplaced. However, the shop supervisor recalls that 230 tune-ups were completed during the week, and the controller recalls the following variance data relating to tune-ups Labor rate variance Labor spending variance S 424 F S 723 U Required: 1. Determine the number of actual labor-hours spent on tune-ups during the week. 2. Determine the actual hourly rate of pay for tune-ups last week. (Round your answer to 2 decimal places Actual labor hours Actual hourly rate 1. hours 2. per hourExplanation / Answer
1) Calculate actual hours :
Actual cost = standard cost+unfavourable labour spending variance
= (230*9.30)+723
Actual cost = 2862
Labour rate variance = (Standard price-actual price)actual hours
424 = (6.20X-2862)
-6.20X = -3286
X(actual hours) = 530 Hours
b) Actual rate = 2862/530 = $5.40 per hour
