max_coefficients = (4.60 * 0.86 + 3.85 * 1 + 3.75 * 1 + 3.65 * 1) = 15.19266
p1 = (74.77 * 4 * 0.29 + 1000 * 2.10 * 0.71 + 371.43 * 1.90 * 1 + 0 + 0) / (4 * 0.29 + 2.10 * 0.71 + 1.90 * 1 + 1 + 1) = 350.1818020642444
p2 = (1000 * 2.10 * 0.71 + 371.43 * 1.90 * 1 + 74.77 * 4 * 0.29) / max_coefficients = 150.8083508746987
score = 350.1818020642444 * 0.5 + 150.8083508746987 * 0.5 = 250.49507646947154
