Question 251436
Juice X is 20% real fruit juice while Juice Y is 70% real fruit juice. How many liter of each should be mixed together to make 80 liters that is 50% real juice?
------------------------
Equation:
real + real = real
0.20x + 0.70(80-x) = 0.50*80
Multiply thru by 100 to get:
20x + 70*80 - 70x = 50*80
-50x = -20*80
x = 160/5
x = 32 liters (amt. of 20% juice needed in the mixture)
---
80-x = 48 liters (amt. of 70% juice needed in the mixture)
