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, 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 21,000 speakers? (Do not round intermediate calculations.) 1.b. By how much does directlabour cost differ from the cost that was incurred? (Indicate the effect of variance by selecting "F" for fovourable, "U" for unfavourable, and "None" for no effect (l.e., zero vorionce).) 2. Break down the difference in cost from requirement 1-b above into a labour rate variance and a labour efficiency variance. (Indicate the effect of each variance by selecting "F" for fovourable, "U" for unfovourable, and "None" for no effect (i.e., zero variance).) 3. The budgeted variable manufacturing overhead rate is $3.00 per direct labour-hour. During July, the company incurred $27,510 in variabie manufacturing overhead cost. Compute the variable oveithead spending and efficiency variances for the month. (Indicate the effect of each variance by selecting "F" for favourable, "U" for unfovourable, and "None" for no effect (i.e., zero variance).)
