As the management accountant for Superior Log Cabins, Inc. you have been asked to attend a planning meeting for the 2020 season. The owner specifically wants to know how many log cabins must be sold to earn a profit of $450,000 in 2020. The company makes three models of cabins: deluxe, standard, and basic.

At the end of 2019, the local utility company began charging Superior as a mixed cost: an annual fee plus a variable cost for each kilowatt of power the company uses (rather than solely at a fixed rate). Each cabin, regardless of model type, requires approximately 8,000 kilowatt hours of electricity. The company needs to add that new utility cost to the projected income statement for 2020. Note that the current fixed cost estimate of $18,000 per cabin model in Table 2 is NOT related to the new utility cost, but is a fixed manufacturing overhead cost that will continue to exist along with the fixed portion of the new utility cost.

Cabins are constructed at three separate locations (one for each model), so the utility company will estimate costs separately for each model type. Thus, the total fixed cost and the variable cost per unit will respectively be the same at each of the three locations. The owner estimates that sales in 2019 will be 25 basic cabins, 35 deluxe cabins, and 55 standard cabins, and they will produce exactly that quantity.

The current selling price per unit is $79,000 for basic, $112,000 for deluxe, and $91,000 for standard cabins and will not increase next year. Assume that there are $150,000 of fixed administrative expenses per model and $5,500 of variable selling expenses for each cabin sold, no matter what model it is. The company uses job order costing.

4	Estimate the 2020 cost of utilities using the least-squares regression method.
	4a. Use the SLOPE function and the INTERCEPT function to determine a cost equation for utilities.
	4b. Using your cost equation and the total predicted number of kilowatt hours needed in 2020, clearly provide an estimate of the utility costs for Basic model cabins.
	4c. Use the FORECAST.LINEAR function and the total predicted number of kilowatt hours needed in 2020 to estimate the utility costs for Basic model cabins.
