In 2006, Milton Thayne, president of Carbondale Electronics, received a report indicating that quality costs were 31 percent of sales. Faced with increasing pressures from imported goods, Milton resolved to take measures to improve the overall quality of the company's products. After hiring a consultant in 2007, the company began an aggressive program of total quality control. At the end of 2010, Milton requested an analysis of the progress the company had made in reducing and controlling quality costs. The accounting department assembled the following data:

Required:
1. Compute the quality costs as a percentage of sales by category and in total for each year.
2. Prepare a multiple-year trend graph for quality costs, both by total costs and by category. Using the graph, assess the progress made in reducing and controlling quality costs. Does the graph provide evidence that quality has improved? Explain.
3. Using the 2006 quality cost relationships (assume all costs are variable), calculate the quality costs that would have prevailed in 2009. By how much did profits increase in 2009 because of the quality improvement program? Repeat for2010.
