Determining Unit Costs, Variance Analysis, and Interpretation Big Dog Company, a manufacturer of dog food, produces its product in 1,000-bag batches. The standard cost of each batch consists of 8,000 pounds of direct materials at $0.40 per pound, 48 direct labor hours at $8.75 per hour, and variable overhead cost (based on machine hours) at the rate of $10 per hour with 16 machine hours per batch. The following variable costs were incurred for the last 1,000-bag batch produced: Direct materials 8,300 pounds costing $ 3,154 were purchased and used Direct labor 45 hours costing $ 450 Variable overhead $ 225 Machine hours used 18 hours (a) Determine the actual and standard variable costs per bag of dog food produced, separated into direct materials, direct labor, and variable overhead.
