max_coefficients = (4.20 * 1 + 4.05 * 1 + 3.75 * 1 + 2.80 * 1) = 14.8
p1 = (1000 * 1.20 * 0.57 + 545.45 * 1.10 * 1 + 363.64 * 1.10 * 1 + 0 + 0) / (1.20 * 0.57 + 1.10 * 1 + 1.10 * 1 + 1 + 1) = 345.0246434477902
p2 = (1000 * 1.20 * 0.57 + 545.45 * 1.10 * 1 + 363.64 * 1.10 * 1) / max_coefficients = 113.89729729729729
score = 345.0246434477902 * 0.5 + 113.89729729729729 * 0.5 = 229.46097037254373
