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: Standard Standard Standard Job Motor tune-up Hours 3.00 Cost $21.00 $7.00 The record showing the time spent in the shop last week on motor tune-ups has been misplaced. However, the shop supervisor recalls that 250 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 $1,540 F $2,940 F Required 1. Determine the number of actual labor-hours spent on tune-ups during the week. tual labor hours hours 2. Determine the actual hourly rate of pay for tune-ups last week. (Round your answer to 2 decimal places.) Actu ? leerhour al hourly rate

Solution

1) Labour efficiency variance = 2940-1540 = 1400 F

Labour efficiency variance = (Standard hour-actual hour)standard rate

1400 = (250*3-X)7

1400 = 5250-7X

7X = 3850

X(actual hour) = 550 Hours

2) Labour rate variance = (Standard rate-actual rate)actual hours

1540 = (7*550-550X)

550X = 2310

X(actual rate) = 4.20 per hour
