max_coefficients = (4.60 * 1 + 4 * 1 + 3.65 * 1 + 3.05 * 1) = 15.3
p1 = (1000 * 1.80 * 0.57 + 391.30 * 1.40 * 0.71 + 747.66 * 4 * 1 + 0 + 0) / (1.80 * 0.57 + 1.40 * 0.71 + 4 * 1 + 1 + 1) = 549.3501931858096
p2 = (747.66 * 4 * 1 + 1000 * 1.80 * 0.57 + 391.30 * 1.40 * 0.71) / max_coefficients = 288.2666666666667
score = 549.3501931858096 * 0.5 + 288.2666666666667 * 0.5 = 418.8084299262382
