An import car dealer sells three models of a car. The retail prices and the current dealer invoice prices (costs) for the basic models and options indicated are given in the following two matrices (where "Air" means air-conditioning). We define the markup matrix to be

MN

(markup is the difference between the retail price and the dealer invoice price). Suppose that the value of the dollar has had a sharp decline and the dealer invoice price is to have an across-the-board 15% increase next year. To stay competitive with domestic cars, the dealer increases the retail prices 10%. Calculate a markup matrix for next year's models and the options indicated.

		Dealer invoice price								Retail Price

Model A		$30,922	$2333	$835	$452			Model A		$35,860	$2882	$1451	$624
Model B		$34,865	$1563	$696	$394		=N	Model B		$39,660	$1844	$836	$511		=M
Model C		$41,864	$2859	$1181	$679			Model C		$45,591	$3383	$1428	$852
