Q:
Una compañía elabora dos productos. El producto \( T \) requiere por unidad \( 1 / 2 \)
hora en armado, 9 minutos en control de calidad y \( \$ 10000 \) en materias primas.
El producto M requiere por unidad 20 minutos en labores de armado, \( 1 / 5 \) de
hora en control de calidad y \( \$ 6000 \) en materias primas. Actualmente el personal
de la compañía permite a lo sumo un total de 90 horas para armado y 80 horas
para control de calidad, al día. El primer producto descrito tiene un valor de
mercado (precio de venta) de \( \$ 80000 \) por unidad y para el segundo este valor
corresponde a \( \$ 50000 \) por unidad. Adicionalmente se estima que el limite
máximo de ventas al día del producto T es de 200 unidades y no se tiene un
limite máximo de ventas diarias para el producto M .
Resuelva gráficamente y determine los niveles de producción que permiten
maximizar las utilidades de la compañia y presente su respuesta a la empresa
debidamente analizada.
