OC userin Accounting·5 Dec 2017EXERCISE 2-14 High-Low Method; Predicting Cost [L02-4, LO2-5] The Lakeshore Hotel's guest-days of occupancy and custodial supplies expense over the last seven months were: Guest-Days of Occupancy Custodial Supplies Expense Month March ....... April May June ...... July ........ August September ...... 4,000 6,500 8,000 10,500 12,000 9,000 7,500 $7,500 $8,250 $10,500 $12,000 $13,500 $10,750 $9,750 . . . . . . Guest-days is a measure of the overall activity at the hotel. For example, a guest who stays at the hotel for three days is counted as three guest-days. Required: 1. Using the high-low method, estimate a cost formula for custodial supplies expense. 2. Using the cost formula you derived above, what amount of custodial supplies expense would you expect to be incurred at an occupancy level of 11,000 guest-days? 3. Prepare a scattergraph using the data given above. Plot custodial supplies expense on the ver- tical axis and the number of guest-days occupied on the horizontal axis. Draw a straight line 4. through the two data points that correspond to the high and low levels of activity. Make sure your line intersects the Y-axis. Comment on the accuracy of your high-low estimates assuming a least-squares regression analysis estimated the total fixed costs to be $3,973.10 per month and the variable cost to be $0.77 per guest-day. How would the straight line that you drew in requirement 3 differ from a straight line that minimizes the sum of the squared errors? Using the least-squares regression estimates given in requirement 4, what custodial supplies expense would you expect to be incurred at an occupancy level of 11,000 guest-days? 5. Net operating income. $ 6,000 $ 18,000 $ 30,000 Required: 1. Identify each of the company's expenses (including cost of goods sold) as either variable, fixed, or mixed. 2. Using the high-low method, separate each mixed expense into variable and fixed elements. State the cost formula for each mixed expense. 3. Redo the company's income statement at the 5,000-unit level of activity using the contribution format.

The company, which is privately owned, has approached a bank for a loan to help it finance its growth. The bank requires financial statements before approving such a loan. You have been asked to help prepare the financial statements and were given the following list of costs: 1. Depreciation on salespersons' cars. 2. Rent on equipment used in the factory. 3. Lubricants used for machine maintenance. 4. Salaries of personnel who work in the finished goods warehouse. 5. Soap and paper towels used by factory workers at the end of a shift. 6. Factory supervisors' salaries. 7. Heat, water, and power consumed in the factory. 8. Materials used for boxing products for shipment overseas. (Units are not normally boxed.) 9. Advertising costs. 10. Workers' compensation insurance for factory employees. 11. Depreciation on chairs and tables in the factory lunchroom. 12.
