El administrador de una cafetería sabe que vende diariamente 50 litros de jugo mixto. Para elaborar este jugo se emplean dos pre
Nina [5.8K]

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:

  • 50 L * 10/100 = 5 L

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:

  • x + y = 50
  • x = 50 - y

Reemplazamos x en la segunda ecuación:

  • (50-y)*5/100 + y*25/100 = 5

Y despejamos <em>y</em>:

  • 2.5 - 0.05y + 0.25y = 5
  • 0.20y = 2.5
  • y = 12.5

Usando ese valor de y, calculamos x:

  • x + 12.5 = 50
  • x = 37.5

Whats 3 2/3 as im proper fraction
Flura [38]
11/3. This is because you multiply the denominator by the mixed number. Than you add the numerator to that. Put that number over the denominator you had in the original problem. Hope this helps!
