Affordable Electronics Inc. manufactures medium-quality, 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 Hours 18 minutes (0.30 hours) Standard Rate per Hour $10.00 Standard Cost $3.00 During July 6,550 hours of direct labour time were recorded to make 21,000 units. The direct labour cost totalled $69,430 for the month Requirect 1-a. What direct labour cost should have been incurred to make the 21000 speakers? (Do not round intermediate calculations.) Direct labour.com 1-b. By how much does direct labour cost differ from the cost that was incurred? (Indicate the effect of variance by selecting "P" for favourable. "U" for unfavourable, and "None" for no effect (.e., zero variance) Total vallan 2. Break down the difference in cost from requirement i-bobove 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 effectie, zero variance)) Labour rate variance Latour officiency variance 3. The budgeted variable manufacturing overhead rate is $4.00 per direct labour hour. During July, the company incurred $27,510 in variable manufacturing overhead cost.
