Need more info. What are you trying to look for?
0.555x91,000=50,505 are under 40
91,000-50,505=40,495 are over 40
I do believe that the 3 vertices form a right triangle. I mean it uses perpendicular lines to see if you can form a right triangle with vertices. I really do hope I helped ^^
49.5-40 = 9.5
so 40 x 8.18 = 327.20
8.18 x 1.5 = 12.27
12.27 x 9.5 = 116.57
327.20 + 116.57 = $443.77
