Step-by-step explanation:
Answer:
Se necesitan 37.5 litros del preparado que contiene 5% de jugo natural, y 12.5 litros del que contiene 25%.
Step-by-step explanation:
Primero calculamos la cantidad total de jugo natural que se necesita, a partir del volumen de jugo mixto que se quiere vender:
Ahora, que X sean los litros del preparado con jugo de 5%, y que Y sean los litros del preparado con jugo de 25%:
La suma de ambos preparados tiene que ser 50 L:
1. x + y = 50
La suma del jugo natural tiene que ser 5:
2. x*5/100 + y*25/100 = 5
Por lo que tenemos <em>un sistema de dos ecuaciones y dos incognitas</em>.
Expresamos x en términos de y:
Reemplazamos x en la segunda ecuación:
- (50-y)*5/100 + y*25/100 = 5
Y despejamos <em>y</em>:
Usando ese valor de y, calculamos x:
