In one kilogram of meat of two colours is 650 g of pork, the rest is chicken. One kilogram of pork is 40 CZK more expensive than a kilogram of chicken. How many CZK cost one kilogram of chicken meat so that the price of one kilogram of meat of two colours is a maximum of 81 CZK.

Correct result:

k =  55 Kc/kg

Solution:

V=650 kg K=1000V=1000650=350 kg    v=40+k 81 (K+V)=V v+K k v=40+k 81 (350+650)=650 v+350 k  kv=40 350k+650v=81000  k=55=55 Kc/kg v=95
