The standard cost sheet for Chambers Company, which manufactures one product, follows: $ 140 100 85 Direct materials, 40 yards $3.50 per yard Direct labor, 5 hours at $20 per hour Factory overhead applied at 85% of direct labor (variable costs = $60, fixed costs = $25) Variable selling and administrative Fixed selling and administrative Total unit costs 57 $ 463 Standards have been computed based on a master budget activity level of 30,500 direct labor-hours per month. Actual activity for the past month was as follows: Materials used Direct labor Total factory overhead Production 245,000 yards at $3.60 per yard 30,900 hours at $21.60 per hour $560,000 5,700 units Required: Prepare variance analyses for the variable and fixed costs. Materials are purchased as they are used. (Do not round intermediate calculations. Indicate the effect of each variance by selecting "F" for favorable, or "U" for unfavorable. If there is no effect, do not select either option.)
