A department store marks up the price of a power drill by 32 % of the price from the manufacture. The price P x in $ to a customer after a 6.5 % sales tax is given by P x = 1.065 x + 0.32 x , where x is the cost of the drill from the manufacture, Evaluate P 189 and interpret the meaning in the context of this problem.
