q1 = 75 - 33·p1 + 5·p2
q2 = 52 - 2·p1 - 6·p2
G = q1 * (p1 - 2) + q2 * (p2 - 5)
G = (75 - 33·p1 + 5·p2) * (p1 - 2) + (52 - 2·p1 - 6·p2) * (p2 - 5)
G = - 33·p1^2 + 3·p1·p2 + 151·p1 - 6·p2^2 + 72·p2 - 410
dG / dp1 = - 66·p + 3·q + 151 = 0
dG / dp2 = 3·p - 12·q + 72 = 0
Lösung: p1 = 2.59 GE ∧ p2 = 6.65 GE
G = - 33·2.59^2 + 3·2.59·6.65 + 151·2.59 - 6·6.65^2 + 72·6.65 - 410 = 24.86 GE
q1 = 75 - 33·2.59 + 5·6.65 = 22.78 ME
q2 = 52 - 2·2.59 - 6·6.65 = 6.92 ME
