Rafferty Company, which uses the high-low method to analyze cost behavior, has determined that machine machine hour usage data for the first six months of the year follow: Using the high-low method, answer the following questions: What is the variable utilities cost per machine hour? What is the fixed cost of utilities each month? Let's begin by determining the formula that is used to calculate the variable cost (slope). Variable cost (slope). Using the high-low method, the variable utilities cost per machine hours is $ What is the fixed cost of utilities each month? = fixed cost Rafferty Company, which uses the high-low method to analyze cost behavior, has determined that machine machine hour usage data for the first six months of the year follow: Using the high-low method, answer the following questions: What is the variable utilities cost per machine hour?
