See NFPA 13: 11.2.3.2.7.1 the next section below the #30% increases. It tells you to compound the adjustments. 1500 + 30%= 1950, 1950 + 30%= 2535.

Per code I need to increase the area of operation 30% for the dry system and another 30% for the roof pitch. I'm fine with that, but which answer is the right one? 1500 + 30% + 30% = 2535 OR 1500 + 60% = 2400 ???????? It's gonna be a long week....
