max_coefficients = (4.60 * 1 + 3.85 * 1 + 3.75 * 1 + 3.65 * 1) = 15.85
p1 = (290.32 * 1.80 * 0.43 + 130.43 * 2.10 * 1 + 0 + 0 + 0) / (1.80 * 0.43 + 2.10 * 1 + 1 + 1 + 1) = 84.79804069842697
p2 = (130.43 * 2.10 * 1 + 290.32 * 1.80 * 0.43) / max_coefficients = 31.412618296529967
score = 84.79804069842697 * 0.5 + 31.412618296529967 * 0.5 = 58.10532949747847
