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: 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. Requlrect: 1-e. What direct labour cost should have been incurred to make the 16,000 speakers? (Do not round Intermedlate calculetlons.) 1-b. By how much does direct labour cost differ from the cost that was incurred? (Indleate the effect of verlence by selecting "F" for favourable, "U" for unfevourable, and "None" for no effect (l.e., zero varlance).) 2. Break down the difference in cost from requirement 1-b above into a labour rate variance and a labour efficiency variance. (Indlcate the effect of each varlance by selecting "F" for favourable, "U" for unfevourable, and "None" for no effect (I.e., zero varlance).) 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 variances for the month. (Indlcate the effect of each varlence by selecting "F" for fevourable, "U" for unfavourable, and "None" for no effect (I.e., zero varlence).)
