However, the shop supervisor recalls that 48 tune-ups were completed during the week, and the controller recalls the following variance data relating to tune-ups: Labour rate variance Total labour variance $128 F 134 U Required: 1. Determine the number of actual labour-hours spent on tuneups during the week. (Round your answer to the nearest whole number.) Actual labour-hours hours 2. Determine the actual hourly rate of pay for tuneups last week. (Hint. A useful way to proceed would be to work from known to unknown data either by using the variance formulas or by using the columnar format shown in Exhibit 11-5.) (Round intermediate calculations to the nearest whole number and final answer to 2 decimal
