One canned orange juice is 25% orange juice another is 5% orange juice. How many liters of each should be mixed together in order to get 20 L that is 8% orange juice

 (3)

Replcaing equation (3) into equation (2) we got:

And solving for Y we got:

And solving for X from equation (3) we got:

So we need 3L of orange juice with 25% of concentration and 17 L of orange juice with 5% of concentration

Step-by-step explanation:

For this problem we can work with the concentration of water and orange juice.

Let X the amount for the orange juice with 25% content and Y the amount for the orange juice with 5% of content

Using the concentration of orange juice we have:

 (1)

And for the water we have:

 (2)

If we solve for X from equation (1) we got:

 (3)

Replcaing equation (3) into equation (2) we got:

And solving for Y we got:

And solving for X from equation (3) we got:

So we need 3L of orange juice with 25% of concentration and 17 L of orange juice with 5% of concentration
