Una empresa maderera fabrica tableros de dos tipos, DM y aglomerado, a partir de madera triturada. Para producir 1 m21\,\text{m}^2 de tablero DM se consumen 10 m310\,\text{m}^3 de madera triturada y se obtiene un beneficio de 10 €10\,\text{€}. Para producir 1 m21\,\text{m}^2 de tablero aglomerado se consumen 30 m330\,\text{m}^3 de madera triturada y se obtiene un beneficio de 20 €20\,\text{€}. La empresa puede fabricar diariamente como máximo 12 m212\,\text{m}^2 de tableros DM y 18 m218\,\text{m}^2 de tableros de aglomerado. Además, la capacidad total de la empresa limita la producción conjunta a 26 m226\,\text{m}^2 diarios y dispone de 600 m3600\,\text{m}^3 de madera triturada al día. Determine cuántos metros cuadrados de cada tipo de tablero deben producirse diariamente para maximizar el beneficio total y calcule cuál es ese beneficio.
