Account Analysis Method Penny Hassan runs the Shear Beauty Salon near a college campus. Several months ago, Penny used some unused space at the back of the salon and bought two used tanning beds. She hired a receptionist and kept the salon open for extended hours each week so that tanning clients would be able to use the benefits of their tanning packages. After three months, Penny wanted additional information on the costs of the tanning area. She accumulated the following data on four accounts: Supplies and Maintenance Wages January February $1,816 1,710 March 1,833 $1,458 1,896 4,041 Number Equipment Depreciation Tanning of Minutes Electricity $129 $362 4,104 Visits 426 129 129 402 684 3,978 6,780 390 582 Penny decided that wages and equipment depreciation were fixed. She thought supplies and maintenance would vary with the number of tanning visits and that electricity would vary with the number of tanning minutes. Required: 1.
