Montoursville Control Company, which manufactures electrical switches, uses a standard-costing system. The standard production overhead costs per switch are based on direct-labor hours and are as follows Variable overhead (5 direct-labor hours e $13.00 per hour) Fixed overhead (5 direct-labor hours $19.00 per hour)* $ 65 95 Total overhead $160 Based on capacity of 303,500 direct-labor hours per month The following information is available for the month of October Variable overhead costs were $4,380,000. .Fixed overhead costs were $6,675,000. 57,700 switches were produced, although 60,700 switches were scheduled to be produced. 282,000 direct-labor hours were worked at a total cost of $4,525,000. Required: Compute the variable-overhead spending and efficiency variances and the fixed-overhead budget and volume variances for October. (indicate the effect of each variance by selecting "Favorable" or "unfavorable". Select "None" and enter"0" for no effect (i.e., zero variance).)
