The short answer
The approved whole-home baseline can be multiplied by the number of openings to create a starting project range, with an approved location factor when one is available. Size, style, frame, glass, method, damage, access, finish, and local requirements can make two equal-count projects materially different, so the final price requires a measured written quote.
Published ranges are national baselines or clearly identified geographic adjustments from the active Window Replacers pricing model.
