K(x) = 6x + 72
E(2) = 45
E(4) = 84
E(8) = 144
4·a + 2·b + c = 45
16·a + 4·b + c = 84
64·a + 8·b + c = 144
Kontroll-Lösung: a = -0.75 ∧ b = 24 ∧ c = 0
E(x) = -0.75·x^2 + 24·x
G(x) = E(x) - K(x) = - 0.75·x^2 + 18·x - 72
Gewinnzone G(x) = 0
5.07 ME < x < 18.93 ME
Gewinnmaximum G'(x) = 0
x = 12 ME
G(12) = 36 GE
