Overhead Application, Overhead Variances, Journal EntriesPlimpton Company produces countertop ovens. Plimpton uses a standard costing system. The standard costing system relies on direct labor hours to assign overhead costs to production. The direct labor standard indicates that two direct labor hours should be used for every oven produced. The normal production volume is 100,000 units. The budgeted overhead for the coming year is as follows:Fixed overhead $760,000Variable overhead 446,000**At normal volume. Plimpton applies overhead on the basis of direct labor hours. During the year, Plimpton produced 97,000 units, worked 196,000 direct labor hours, and incurred actual fixed overhead costs of $770,400 and actual variable overhead costs of $437,580.Required:1. Calculate the standard fixed overhead rate and the standard variable overhead rate. Round your answers to the nearest cent. Use rounded answers in the subsequent computations. Standard fixed overhead rate $ per direct labor hourStandard variable overhead rate $ per direct labor hour2. Compute the applied fixed overhead and the applied variable overhead. Use the application rates from part (1) in your calculations. Fixed $Variable $What is the total fixed overhead variance?$ UnfavorableWhat is the total variable overhead variance?$ Unfavorable3. Break down the total fixed overhead variance into a spending variance and a volume variance. Spending Variance $ UnfavorableVolume Variance $ Unfavorable4. Compute the variable overhead spending and efficiency variances. Spending Variance $ UnfavorableEfficiency Variance $ Unfavorable5. Now assume that Plimpton’s cost accounting system reveals only the total actual overhead. In this case, a three-variance analysis can be performed. Using the relationships between a three- and four-variance analysis, indicate the values for the three overhead variances. Volume variance $ UnfavorableVariable overhead efficiency variance $ UnfavorableSpending variance $ UnfavorableFeedback6. Prepare journal entries (1) to apply overhead to production, (2) to record the actual overhead costs incurred, (3) to record the variable and fixed overhead variances, and (4) to close the variance accounts at the end of the year. Assume variances are closed to Cost of Goods Sold. If an amount box does not require an entry, leave it blank or enter "0".
