max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (578.95 * 2.10 * 1 + 296.30 * 2.30 * 1 + 555.56 * 2.30 * 1 + 0 + 0) / (2.10 * 1 + 2.30 * 1 + 2.30 * 1 + 1 + 1) = 364.948275862069
p2 = (555.56 * 2.30 * 1 + 578.95 * 2.10 * 1 + 296.30 * 2.30 * 1) / max_coefficients = 231.7554744525547
score = 364.948275862069 * 0.5 + 231.7554744525547 * 0.5 = 298.35187515731184
