We are using regression to predict cost behavior. Our X is units and y is direct material cost. How would one describe direct materials? the cost object the cost driver the y-intercept the slope of he line What is a fixed cost? It stays the same in total and in unit cost over the relevant range It stays the same in total but varies per unit It stays the same per unit but varies in total All of these describe a fixed cost How would one likely describe the nails used to construct a house? as direct material as indirect material (overhead) as a fixed cost as a period cost What is the main reason we do not use actual fixed overhead in job order costing? We cannot trace it to a job We could trace it bit it would be too expensive Which of the following companies would not be likely to use a job order system? construction company a ship building company a soda bottling plant all of the above would likely use job order
