D. 15 %

En esta pregunta, debemos aplicar el concepto de porcentaje, definido de la siguiente manera para el caso en cuestión:

n =100\,\% - \frac{n_{E}}{n_{T}}\times 100\,\% (1)

Donde:

  • n_{E} - Cantidad de estudiantes que fueron de excursión.
  • n_{T} - Cantidad total de estudiantes de la escuela.
  • n - Porcentaje de estudiantes que faltaron a la excursión.

Si sabemos que n_{E} = 1088 y n_{T} = 1280, entonces la cantidad de estudiantes que faltaron a la excursión fueron:

n = 100\,\% -\frac{1088}{1280}\times 100\,\%

n = 15\,\%

15 % de los alumnos faltó a la excursión. Por ende, la opción correcta es D.
