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
