I have a question in regards to the "mixture problems made easy" file. In that file we have a question which goes as follows:

"How many liters of a solution that has 15% salt must be added to 5 liters of a solution that has 8% salt, so that the resulting mixture has 10% salt?"

I came up with:

x= liters of 15% solution

15x+5*8=(x+5)*10

which gives x=2 liters. However, the solution in the file is 2,5 liters, can anybody please tell me which one is correct?
