Problem 3 Variable Overhead Variances [L04] Order-Up Company provides customer help centre services for online merchants. The company maintains catalogues and service manuals for stock items carried by its online retail clients. When a client receives a product inquiry or service request from a customer, the request is forwarded to Order-Up, which responds to the customer inquiry on behalf of the online retail client. The company uses a predetermined variable overhead rate based on direct labour-hours. In the most recent month, 35,000 inquiry requests were responded to and solutions provided to customers, using 5,700 direct labour-hours. The company incurred a total of $7,125 in variable overhead costs.
