Alfordable 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, 2,950 hours of direct labour ume were recorded to make 14,000 unils. The direct labour cost totalled $39.530 for the month Requirect. 1.0. What direct labour cost should have been incurred to make the 14,000 speakers? (Do not round intermediote calculations.) 1.b. Hy how much does direct labour cost differ from the cost that was incurred? (Indicate the effect of variance by selecting "F" for favouroble, "U' for unfevouroble, end "None" for no effect (l.e., tero variance).) 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 eoch voriance by selecting " F " for favourable, " U " for unfovourable, and "None" for no effect (i,e., zero varionce).) 3. The budgeted variable manufacturing overhead rate is $3.00 per direct labour-hour. During July, the company incutred $9.145 in variable manufacturing overhead cost. Compute the variable overiead spending and efficiency varlances for the month, (indicote the offect of eoch variance by selecting "F" for fovourable, " U " for unfavourable, ond "None" for no effect (Le., zero voriance)
