O fabrico de cada pão do tipo B requer 0,075 kg de farinha de trigo e 0,02 kg de farinha de centeio. Cada pão deste tipo dá um lucro Kz de 0,20. Num certo dia, a SHOPRITE dispõe de 6,9 kg de farinha de trigo e de 2,4 kg de farinha de centeio para fabricar estes dois tipos de pão. Admita que, nesse dia, uma certa pastelaria compra todos os pães dos tipos A e B produzidos pela SHOPRITE.
