The price of stock A at 9 AM is $12.73.  Since then, the price has been increasing at the rate of $0.06 each hour.  At noon the price of stock B was $13.48.  It begins to decrease at the rate of $0.14 each hour.  If the two rates continue, in how many hours will the prices of the two stocks be the same?

• 12.73x + .06 = 13.48x - 0.14
• 12.73 + .06x = 13.48 - 0.14x
• 12.73 - .06x = 13.48 - 0.14x
• 12.73 + .06x = 13.48 + 0.14x
