Answer:
<em>El administrador debe usar 37.5 litros de jugo al 5% y 12.5 litros de jugo al 25%.</em>
Step-by-step explanation:
<u>Sistemas de Ecuaciones</u>
Llamamos:
x = litros de jugo al 5% natural
y = litros de jugo al 25% natural
El administrador de la cafetería desea hacer 50 litros de jugo, luego:
x + y = 50 [1]
Esos 50 litros de jugo deben tener 10% de jugo natural. Como cada parte de x aporta 5% y cada parte de y aporta 25%:
5x + 25y = 10*50 = 500
Dividimos entre 5:
x + 5y = 100 [2]
Restamos [2] menos [1]:
4y = 50
y = 50/4 = 12.5
De [1] tenemos que:
x = 50 - y = 50 - 12.5 = 37.5
El administrador debe usar 37.5 litros de jugo al 5% y 12.5 litros de jugo al 25%.
