A manufacturing company that has only one product has established the following standards for its variable manufacturing overhead. The company bases its variable manufacturing overhead standards on direct labor-hours. 4.60 DLHS Standard hours per unit of output Standard variable overhead rate $11.55 per DLH The following data pertain to operations for the last month: Actual direct labor-hours Actual total variable manufacturing overhead cost Actual output $ 8,500 DLHS 95,930 1,700 units What is the variable overhead efficiency variance for the month? Multiple Choice 0 $6,753 U o $3,112 U $2.120 O 0 $6,753 F $6753 0 $7,854 U The following data have been provided by Lopus Corporation: Budgeted production Standard machine-hours per unit Standard lubricants Standard supplies $ $ 4,500 units 4.6 machine-hours 6.10 per machine-hour 4.80 per machine-hour Actual production Actual machine-hours Actual lubricants (total) Actual supplies (total) 4,800 units 9,980 machine-hours $ 62,230 $ 47,372 Required: Compute the variable overhead rate variances for lubricants and for supplies. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.)
