Preisfunktion
m = (4.98 - 3.98) / (48 - 60) = -1/12
p(x) = m·(x - Px) + Py = -1/12·(x - 48) + 4.98 = 8.98 - 1/12·x
Erlösfunktion
E(x) = x·p(x) = x·(8.98 - 1/12·x) = 8.98·x - 1/12·x^2
E'(x) = 8.98 - 1/6·x
Maximaler Erlös E'(x) = 0
8.98 - 1/6·x = 0 --> x = 53.88
E(53) = 241.86
E(53.88) = 241.92
E(54) = 241.92
