You and your friend are making 30 liters of sodium water. you have liters of 10% sodium and your friend has liters of 22% sodium. how many of your liters and how many of your friends liters should you mix to make 30 liters of 15% sodium?

You have 17.5 liters of 10% sodium and your friend has 12.5 liters of 22% .

Step-by-step explanation:

We are given that

Total sodium water=30 L

Let you have sodium water=x of 10%

Your friend has sodium water =(30-x) of 22%

We have to find that how many of your  liters and your friend liters should you mix to make 30 liters of 15% sodium.

According to question

x of 10%+(30-x) of 22%=30 of 15%

Multiply by 100 on both sides then, we get

You have 17.5 liters of 10% sodium

Your friend has liters of 22% sodium=30-17.5=12.5 L
