A firm has applies variable overhead with a standard rate of $14 per direct labor hour (assume there is no fixed overhead for this problem). The firm's static budget predicted 5.200 finished goods units (and the standard is for 0.5 direct labor hours to be used per finished good unit). The firm's finished goods produced were 5,000, and the total actual variable overhead costs were $35,000. What is the firm's variable overhead price variance (round final answer to nearest cent if necessary)? O a. $0 O b. Cannot be determined because we lack a standard rate. C. $1,400 favorable O d. cannot be determined because we don't know the actual direct labor hours
