Samuel Hopkins is a cost accountant and business analyst for Dallas Design Company (DDC), which manufactures expensive brass doorknobs. DDC uses two direct-cost categories: direct materials and direct manufacturing labour. Hopkins feels that manufacturing overhead is most closely related to material usage. Therefore, DDC allocates manufacturing overhead to production based upon kilograms of materials used. Requirement 1. For the month of April, compute the variances, indicating whether each is favourable (F) or unfavourable (U). a. Direct materials price variance (based on purchases) is b. The direct materials efficiency variance is c. The direct manufacturing labour price variance is d. The direct manufacturing labour efficiency variance is e. The variable manufacturing overhead spending variance is f. The variable manufacturing overhead efficiency variance is g. The production-volume variance is h. The fixed manufacturing overhead spending variance is Requirement 2. Can Hopkins use any of the variances to help explain any of the other variances? Give examples. The direct materials price variance indicates that DDC paid for brass than they had planned. If this is because they purchased a quality brass, it may explain why they used than expected (leading to a(n) material efficiency variance). The purchase of this quality of brass may also explain why it took labour time to produce the doorknobs than expected (the Finally, the direct labour price variance could imply that the workers who were hired were exticiences variance). Data table Data table At the beginning of 2017, DDC budgeted annual production of 400,000 doorknobs and adopted the followinq standards for each doorknob
