Ответ:
D. 22
Step-by-step explanation:
Con la información proporcionada sabes que el administrador puede alimentar 220 vacas durante 45 días y puedes deducir que si el número de vacas aumenta el alimento duraría menos días, lo que significa que estas magnitudes son inversamente proporcionales. Por esto, para encontrar la respuesta debes usar una regla de tres inversa:
220 vacas → 45 días
450 vacas → x
x=(220*45)/450
x= 22 días
De acuerdo a esto, la respuesta es que el administrador podrá alimentar a las 450 vacas por 22 días con la misma cantidad de alimento.
