a) G(x) = E(x) -K(x) = p(x)*x - K(x)
G(x) = 1,6*10^13/x^3 - 1,6*10^13/x^4*h
G(h=100) = 1,6*10^13/x^3 - 1,6*10^13/x^4*100 = 1,6*10^13*(1/x^3 -100/x^4)
Gewinnschwelle:
G(x)= 0
x= 100
c) G(x) = 1,6*10^13/x^3- 1,6*10^13*100/x^4
G'(x) = 0
x= 400/3 = 133 1/3
133 1/3/100 -1 = 33 1/3 %
d) G(x=33 1/3, h=100)/(G(x=133 1/3, h =80) = 6750 000 / 4050 000 -1 = 66 2/3 %
