Affordable Electronics inc. manufactures medium quality, reasonably priced wireless speakers for home use. The company ises standards to control its costs. The labour standards that have been set for one speaker are as follows: During July. 3,850 hours of direct labour time were recorded to make 16,000 units. The direct labour cost totalled $61,600 for the month. Required: 1.0. What direct labour cost should have been incurred to make the 16.000 speakers? (Do not round intermediate caiculations.) 1.b. By how much does direct labour cost differ from the cost that was incurred? (Indicate the effect of variance by salecting "F= for fovouroble, "U" for unfovourable, and "None" for no effect (l.e., zero variance).) 2. Break down the difference in cost from requirement 1.b above into a labour rate variance arid a labour efficiency viriance. (indicate the effect of eoch variance by selecting "F" for fovouroble, "U" for unfavourable, and "None" for no effact (l. , z., zero variance). 3. The budgeted variable manufacturing overhead rate is $3.00 per direct labour-hour. During July, the company incurred $13,475 in variable manufacturing overhead cost. Compute the variable overhead spending and efficiency varlances for the month. (Indicate the effeet of each vorionce by selecting "F" for fovourable, "U" for unfovourable, and "None" for no effect (the., fero variancel.)
