Bargain Rental Car offers rental cars in an off-airport location near a major tourist destination in California. Management would like to better understand the variable and fixed portions of its car washing costs. The company operates its own car wash facility in which each rental car that is returned is thoroughly cleaned before being released for rental to another customer. Management believes that the variable portion of its car washing costs relates to the number of rental returns. Accordingly, the following data have been compiled:

Month	Rental Returns		Car Wash Costs
January	2,380		$	10,825
February	2,421		$	11,865
March	2,586		$	11,332
April	2,725		$	12,422
May	2,968		$	13,850
June	3,281		$	14,419
July	3,353		$	14,935
August	3,489		$	15,738
September	3,057		$	13,563
October	2,876		$	11,889
November	2,735		$	12,683
December	2,983		$	13,796

2. Using least-squares regression, estimate the variable cost per rental return and the monthly fixed cost incurred to wash cars. (Round Fixed cost to the nearest whole dollar amount and the Variable cost per unit to 2 decimal places.)

Fixed cost per month - ?

Variable cost per rental return - ?
