The standard production overhead costs per switch are based on direct labor hours and are as follows: Variable overhead (5 direct-labor hours $13.00 per hour) Fixed overhead (s direct-labor hours @ $25.00 per hour) Total overhead $ 65 125 $ 190 "Based on capacity of 309,500 direct-labor hours per month The following information is available for the month of October. Variable overhead costs were $5,820,000 Fixed overhead costs were $8,475,000. . 58,900 switches were produced, although 61,900 switches were scheduled to be produced, 294,000 direct-labor hours were worked at a total cost of $5725,000 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 "O" for no effect (i.e., zero variance).)
