Answer

Answer:

C.

Explanation:

Step1: Establecer la ecuación - inecuación

168 + 12x>480

Step2: Resolver la inecuación para x

12x>480 - 168 12x>312 x > \frac{312}{12} x>26

Step3: Interpretar la solución en el contexto de la gráfica

La solución x > 26 se representa en una recta numérica con un círculo abierto en 26 y la flecha hacia la derecha. La opción C muestra correctamente esta representación.
