Affordable Electronics Inc. manufactures mediumquality, reasonably priced wireless speakers for home use. The company uses standards to control its costs. The labour standards that have been set for one speaker are as follows: Standard Rate Standard Standard Hours per Hour Cost 18 minutes (0.30 hours) $19.00 $5.70 ' During July, 8,880 hours of direct labour time were recorded to make 29,000 units. The direct labour cost totalled $174,936 for the month. Required: 1-a. What direct labour cost should have been incurred to make the 29,000 speakers? (Do not round intermediate calculations.) _:| 1-b. By how much does direct labour cost differ from the cost that was incurred? (Indicate the effect of variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero va riance).) _::| 2. Break down the difference in cost from requirement 1b above into a labour rate variance and a labour efficiency variance. (Indicate the effect of each variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variancel.) Labour rate variance _ 3. The budgeted variable manufacturing overhead rate is $3.00 per direct labourhour. During July, the company incurred $36,408 in variable manufacturing overhead cost. Compute the variable overhead spending and efficiency variances for the month. (Indicate the effect of each variance by selecting "F\" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance).) Variable overhead spending variance - Variable overhead efciency variance
