max_coefficients = (4.10 * 1 + 3.90 * 1 + 3.50 * 1 + 3.45 * 1) = 14.95
p1 = (1000 * 1.20 * 1 + 842.11 * 1.90 * 1 + 0 + 0 + 0) / (1.20 * 1 + 1.90 * 1 + 1 + 1 + 1) = 459.016393442623
p2 = (842.11 * 1.90 * 1 + 1000 * 1.20 * 1) / max_coefficients = 187.29096989966555
score = 459.016393442623 * 0.5 + 187.29096989966555 * 0.5 = 323.1536816711443
