Remnant Carpet Company sells and installs commercial carpeting for office buildings. Remnant Carpet Company uses a job order cost system. When a prospective customer asks for a price quote on a job, the estimated cost data are inserted on an unnumbered job cost sheet. If the offer is accepted, a number is assigned to the job, and the costs incurred are recorded in the usual manner on the job cost sheet. After the job is completed, reasons for the variances between the estimated and actual costs are noted on the sheet. The data are then available to management in evaluating the efficiency of operations and in preparing quotes on future jobs. On October 1, Remnant Carpet Company gave Jackson Consulting an estimate of $3,206 to carpet the consulting firm's newly leased office. The estimate was based on the following data: Estimated direct materials: 40 meters at $31 per meter $ 1,240 Estimated direct labor: 20 hours at $30 per hour 600 Estimated factory overhead (75% of direct labor cost) 450 Total estimated costs $2,290 Markup (40% of production costs) 916 Total estimate $3,206 On October 3, Jackson Consulting signed a purchase contract, and the delivery and installation were completed on October 10.
