The standard cost sheet for Chambers Company, which manufactures one product, follows: Direct materials, 30 yards at $2.00 per yard Direct labor, 5 hours at $20 per hour Factory overhead applied at 80% of direct labor (variable costs = $55; fixed costs = $25) Variable selling and administrative Fixed selling and administrative $ 60 100 80 42 $348 Total unit costs Standards have been computed based on a master budget activity level of 29,000 direct labor-hours per month. Actual activity for the past month was as follows: 200,000 yards at $2.10 per yand Materials used Direct labor Total factory overhead Production 28,500 hours at $21.00 per hour $550,000 5,600 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.)
