Order Up, Inc., provides order fulfillment services for dot.com merchants. The company maintains warehouses that stock items carried by its dot.com clients. When a client receives an order from a customer, the order is forwarded to Order Up, which pulls the item from storage, packs it, and ships it to the customer. The company uses a predetermined variable overhead rate based on direct labor-hours.

In the most recent month, 155,000 items were shipped to customers using 6,200 direct labor-hours. The company incurred a total of $19,530 in variable overhead costs.

According to the companys standards, 0.04 direct labor-hours are required to fulfill an order for one item and the variable overhead rate is $3.20 per direct labor-hour.

Required:
1.	According to the standards, what variable overhead cost should have been incurred to fill the orders for the 155,000 items? How much does this differ from the actual variable overhead cost?

2.	Break down the difference computed in (1) above into a variable overhead rate variance and a variable overhead efficiency variance. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance).) Need help with #2 only!
