via The Moore Company produces and sells a single product. A standard cost card for the product follows: Com weig c) Standard Cost Card - per unit of product Direct materials, 4 metres at $4.00 Direct labour, 1.5 hours at $10.00 Variable overhead, 1.5 hours at $3.00 Fixed overhead, 1.5 hours at $7.00 Standard cost per unit $16.00 15.00 4.50 10.50 $16.00 The company manufactured and sold 18,000 units of product during the year. A total of 70,200 metres of material was purchased during the year at a cost of 54.20 per metre.
