Use the high-low method to determine the laboratory's cost equation for total laboratory overhead. Use **NUVCHUMID Orne year Use your results to predict total laboratory overhead if 3,000 lab tests are performed next month. WA TUSUS to predict totalle 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 MetroFit's operating cost equation. (Round the variable cost to the nearest cent) X+ Use the operating cost equation you determined above to predict total laboratory overhead if 3.000 lab tests are performed next month The total laboratory overhead at a volume of 3,000 tab tests is Number of Lab Tests Performed Total Laboratory Overhead Costs Month 2,700 $22,900 January. February 2,500 $23,500 March 3,500 $29,800 April 4.000 $32,500 May 4,600 $31,100 June 2,000 $22,000 July 2,250 $19, 100 Print Done
