Determining Unit Costs, Variance Analysis, and Interpretation Nestl, manufacturer of Purina Dog Chow, produces its product in 500-bag batches. Assume the standard batch consists of 10,000 pounds of direct materials at $0.25 per pound, 16 direct labor hours at $15 per hour, and variable overhead cost (based on machine hours) at the rate of $20 per hour with 10 machine hours per batch. The following variable costs were incurred for the last 500-bag batch produced:

Direct materials	10,250 pounds costing $2,255 were purchased and used
Direct labor	15 hours costing $231
Variable overhead	$215
Machine hours used	9.5 hours

(a) Determine the actual and standard variable costs per bag of dog food produced, separated into direct materials, direct labor, and variable overhead.
