Question 73047: How many liters of a 20% alcohol solution and a 10% alcohol solution should be mixed to obtain 50 liters of a 12% alcohol solution? Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website! Let x=number of liters of 20% solution, y=# of liters of 10% solution
If we want 50 liters of the combined sum of the 2 solutions it will look like this
Since we want 50 liters of 12% solution it comes to
And to mix the solutions we use the equation (for instance 30% of 10 liters + 20% of 10 liters = 5 liters, this is an example not the answer)
Now use the linear solver to get our answer
