Exercise 5A-2 (Algo) Least-Squares Regression (LO5-11) [The following information applies to the questions displayed below.] 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 2,300 $ 10,300 February 2,500 $ 12,800 March 2,700 April 2,900 $ 13,200 $ 15,500 June $ 21,900 July $ 21,500 August $ 20,400 September $ 22,100 3,800 $ 19,000 2,100 $ 10,000 2,600 $ 11,800 $ 11,100 May 3,600 4,900 5,500 5,300 4,600 October November December 2. Using least-squares regression, estimate the variable cost per rental return and the monthly fixed cost incurred to wash cars. (Roun Fixed cost to the nearest whole dollar amount and the Variable cost per unit to 2 decimal places.) Answer is complete but not entirely correct. $ 2,354 Fixed cost per month Variable cost per rental return $ 3.77
