max_coefficients = (4 * 1 + 3.75 * 1 + 3.05 * 1 + 2.90 * 1) = 13.700000000000001
p1 = (1000 * 1.80 * 0.86 + 391.30 * 1.40 * 1 + 747.66 * 4 * 1 + 0 + 0) / (1.80 * 0.86 + 1.40 * 1 + 4 * 1 + 1 + 1) = 568.1969141586845
p2 = (747.66 * 4 * 1 + 1000 * 1.80 * 0.86 + 391.30 * 1.40 * 1) / max_coefficients = 370.89489051094887
score = 568.1969141586845 * 0.5 + 370.89489051094887 * 0.5 = 469.5459023348167
