The quadratic equation y = –6x2 + 100x – 180 models the store’s daily profit, y, for selling soccer balls at x dollars. The quadratic equation y = –4x2 + 80x – 150 models the store’s daily profit, y, for selling footballs at x dollars. Use a graphing calculator to find the intersection point(s) of the graphs, and explain what they mean in the context of the problem.

Well, let's say it was "x", so that's the 100% then.  312 is today's price, which is 20% more than last year's, therefore 312 is really 100% + 20% or 120%.

if 312 is the 120%, what is "x" anyway?
