Jungemann Company, which uses the high-low method to analyze cost behaviour, has determined that machine hours best predict the company's total utilities cost. The company's cost and machine hour usage data for the first six months of the year follow. (Click the icon to view the data.) Requirements Using the high-low method, answer the following questions: 1. What is the variable utilities cost per machine hour? 2. What is the fixed cost of utilities each month? 3. If Jungemann Company uses 1,270 machine hours in a month, what will its total costs be? Requirement 1. What is the variable utilities cost per machine hour? Determine the formula that is used to calculate the variable cost (slope). Choose the correct answer below. OA. Lowest cost + Lowest volume = Variable cost (slope) OB. Change in volume + Change in cost = Variable cost (slope) OC. Highest cost + Highest volume = Variable cost (slope) OD. Total operating cost - Total variable cost = Variable cost (slope) O E. Change in cost + Change in volume = Variable cost (slope)
