Exercise 6A-1 High-Low Method [LO6-10] The Cheyenne Hotel in Big Sky, Montana, has accumulated records of the total electrical costs of the hotel and the number of occupancy-days over the last year. An occupancy-day represents a room rented for one day. The hotel's business is highly seasonal, with peaks occurring during the ski season and in the summer. Month Occupancy-Days Electrical Costs January 1,736 $ 4,127 February 1,904 $ 4,207 March 2,356 $ 5,083 April 960 $ 2,857 May 360 $ 1,871 June 744 $ 2,696 July 2,108 $ 4,670 August 2,406 $ 5,148 September 840 $ 2,691 October 124 $ 1,588 November 720 $ 2,454 December 1,364 $ 3,529 Required: 1. Using the high-low method, estimate the fixed cost of electricity per month and the variable cost of electricity per occupancy-day. (Do not round your intermediate calculations. Round your Variable cost answer to 2 decimal places and Fixed cost element answer to nearest whole dollar amount.) 2. What other factors in addition to occupancy-days are likely to affect the variation in electrical costs from month to month
