The manager believes that total overhead varies with the number of lab tests 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 EEB (Click the icon to view the data) performed but 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 3,100 lab tests are performed next month. 745 h22 ts 75224 2 o rf-3333423 re th ril ay n ul Use the high-low method to determine CitiFit's operating cost equation.
