The manager of the main laboratory facility at MetroFit Center is interested in being able to predict the overhead costs each month for the lab. The manager believes that total overhead varies with the number of lab tests performed but that some costs remain the same each month regardless of the number of lab tests performed. The lab manager collected the following data for the first seven months of the year. (Click the icon to view the data.) Use the high-low method to determine the laboratory's cost equation for total laboratory overhead. Use your results to predict total laboratory overhead if 2,700 tab tests are performed next month. Let's begin by determining the formula that is used to calculate the variable cost (slope). Variable cost (slope) Now determine the formula that is used to calculate the fixed cost component - Fixed cost Use the high-low method to determine MetroFir's operating cost equation. (Round the variable cost to the nearest cent.) yos 2.700 lab tests are performed next month Use the operating cost equation you determined above to predict total laboratory overhead The total laboratory overhead at a volume of 2.700 lab tests is Choose from any list or enter any number in the input fields and then continue to the next question at MetroFit Center is interested in being able to predict the overhead costs e of lab tests performed but that some costs remain the same each month rega Data Table Total Laboratory Overhead Costs Month January ...
