Gulf Shore Lawn and Garden Maintenance provides two general outdoor services: lawn maintenance and garden maintenance. The company charges customers $18.0 per hour for each type of service, but lawn maintenance has higher variable costs ($10.8 per hour) than garden maintenance ($5.4 per hour) because of fuel expenses incurred to operate lawn-mowing equipment. All employees are paid a fixed monthly salary. A contribution format income statement for a recent month for the two services appears below. During the month, 8,000 hours of lawn maintenance services and 2,000 hours of garden maintenance were provided: Lawn Maintenance Per Hour Garden Maintenance Per Hour Total Sales $ 144,000 $ 18.0 $ 36,000 $ 18.0 $ 180,000 Variable expenses 86,400 10.8 10,800 5.4 97,200 Contributio
