premise: If Chipotle's Q1 revenue had been 6% higher but costs had remained constant (i.e., there had been a price increase and no change in customer behavior), <hypo>%. No wonder some Chipotle stock analysts think EPS growth could hit 40% in the second half of 2014..
hypothesis: <hypo> should be "the company's pre-tax margin would have been 19.9% instead of 15.1"
