Dynamic Solutions provides supply chain services such as warehousing, order picking and shipping services for Ebay merchants. As part of this service, the company maintains warehouses that stock items sold by its clients. When a client merchant receives an order from a customer, Dynamic Solutions receives a real time copy of that order. Using the order information, Dynamic pulls the item from storage, packs it, and ships it to the customer. Dynamic Solutions uses a predetermined variable overhead rate based on direct labor-hours In the most recent month, 185,000 items were shipped to customers using 8,000 direct labor-hours. The company incurred a total of $27,600 in variable overhead costs. According to the company's standards, 0.04 direct labor-hours are required to fulfill an order for one item and the variable overhead rate is $3.50 per direct labor-hour Required: 1. According to the standards, what variable overhead cost should have been incurred to fill the orders for the 185,000 items? How much does this differ from the actual variable overhead cost? (Round labor-hours per item and overhead cost per hour to 2 decimal places.) Number of items shipped Standard direct labor-hours per item Total direct labor-hours allowed Standard variable overhead cost per hour Total standard variable overhead cost Actual variable overhead cost incurred Total standard variable overhead cost Total variable overhead variance 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).)
