Según la información proporcionada, si el muro fuera 30 m más largo, se necesitarían 9 trabajadores más. Esto significa que el número de trabajadores necesarios para pintar una pared de 280 m sería "x + 9". Podemos establecer una proporción para resolver el problema: 250 m / x trabajadores = 280 m / (x + 9) trabajadores Para resolver esta proporción, podemos multiplicar de forma cruzada: 250(x + 9) = 280x 250x + 2250 = 280x 2250 = 30x x = 75 Por lo tanto, inicialmente se emplearon 75 trabajadores para pintar la pared de 250 m.
