Exercise 21-21 (Algo) Volume variance LO P4 Shaw Company produced 700 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 DLH. The flexible overhead budget at an activity level of 700 units shows $27,000 in variable overhead costs and $31,000 in fixed overhead costs. Compute the volume variance. (Indicate the effect of the variance by selecting favorable, unfavorable, or no variance.) Volume Variance Volume variance
