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 it 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.

January	2,400		$	10,600
February	2,500		$	12,900
March	2,700		$	11,400
April	2,900		$	13,700
May	3,600		$	15,800
June	5,000		$	22,500
July	5,500		$	21,800
August	5,400		$	21,200
September	4,700		$	22,400
October	3,900		$	19,900
November	2,200		$	10,300
December	2,700		$	12,800
