max_coefficients = (4.60 * 1 + 3.85 * 1 + 3.75 * 1 + 3.65 * 1) = 15.85
p1 = (391.30 * 1.40 * 0.14 + 747.66 * 4 * 0.43 + 0 + 0 + 0) / (1.40 * 0.14 + 4 * 0.43 + 1 + 1 + 1) = 276.74861531073606
p2 = (747.66 * 4 * 0.43 + 391.30 * 1.40 * 0.14) / max_coefficients = 85.80883280757098
score = 276.74861531073606 * 0.5 + 85.80883280757098 * 0.5 = 181.27872405915352
