The budgeted sales price for dolls was $5.00, and $5.25 for replicas. The estimated production and sales during December was 31,678 dolls and 2,595 replicas. Required D. Assuming MI used a predetermined overhead rate of $2.13 per DLH, compute the variable overhead rate and efficiency variances. MI actually paid $20,852 in total overhead costs, consisting of $17,002 of variable overhead and $3,850 of fixed overhead. How would these variances be interpreted? What might have caused them? Would you consider them large enough to be important? E. How might MI extend its variance analysis to be compatible with activity-based costing if they decided to switch to that method?
