Exercise 23-21 (Algo) Volume variance LO P4 Shaw Company produced 820 units. Its overhead allocation base is DLH and its standard amount per allocation base is 8 DLH per unit. Its standard overhead rate is $10 per DL.H. The flexible overhead budget at an activity level of 820 units $ hows $33,000 in variable overhead costs and $37,000 in fixed overhead costs.
