Meadowlark Industries uses a standard cost accounting system, which utilizes flexible budget procedures for planning and control purposes. The monthly flexible budget for manufacturing overhead costs is $200,000 of fixed costs plus $4.80 per machine hour. Normal capacity of 100,000 machine hours is used to compute the standard fixed manufacturing overhead rate. During December 20X9. plant workers recorded 105,000 actual machine hours. The standard machine hours allowed for good production during December were only 98,500. Actual costs incurred during December were $541,000 of variable manufacturing overhead and $204,500 of fixed manufacturing overhead. REQUIRED: ( 1 ) Using the attached form, calculate the under- or overapplied manufacturing overhead for variable manufacturing overhead and fixed manufacturing overhead for the month of December. Using the attached form, prepare an analysis of the manufacturing overhead variances by computing the following variances. Show supporting computations. (a) Variable manufacturing overhead spending variance. (b) Variable manufacturing overhead efficiency variance. (c) Fixed manufacturing overhead spending variance. (d) Fixed manufacturing overhead volume variance
