Use the high-low method to determine the variable and fixed cost components of Rapid Lube's operating costs. Use this information to project the monthly operating costs for a month in which the company performs 3,600 oil changes. View the data. Use the high-low method to determine the variable and fixed costs components of Rapid Lube's operating cost equation. First identify the high and low amounts that you will use in your calculations. (Hint: For x and y, think about how those values would be graphed to determine which value is "x" and which is "y".) (GY) High 3,800 $ 38,500 Low 2,600 $ 32,500 Identify the formula and then calculate the variable cost component (slope). (Round your answer to the nearest cent.) + Variable cost per unit
