Anda Painting Service specializes in painting tall office buildings. During a recent month, the company worked on three painting projects (the Building A, the Building B and the Building C). The company is interested in controlling the materials costs, namely the paint, used for these painting contracts. In order to provide management with useful cost control information, the company uses standard costs and prepares monthly variance reports. Analysis reveals that the purchasing agent mistakenly purchased poor-quality paint for the Building A project. The Building B project, however, received higher-than-standard-quality paint that was on sale. The Building C project received standard-quality paint. However, the price had increased and a new employee was used to paint the building. Shown below are quantity and cost data for each project.
