max_coefficients = (4.60 * 1 + 4 * 1 + 3.65 * 1 + 3.05 * 1) = 15.3
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 = 32.54183006535948
score = 84.79804069842697 * 0.5 + 32.54183006535948 * 0.5 = 58.669935381893225
