max_coefficients = (4.10 * 1 + 3.50 * 1 + 3.45 * 1 + 3.25 * 1) = 14.3
p1 = (200 * 1.20 * 1 + 789.47 * 1.90 * 1 + 0 + 0 + 0) / (1.20 * 1 + 1.90 * 1 + 1 + 1 + 1) = 285.24590163934425
p2 = (789.47 * 1.90 * 1 + 200 * 1.20 * 1) / max_coefficients = 121.67832167832167
score = 285.24590163934425 * 0.5 + 121.67832167832167 * 0.5 = 203.46211165883295
