8(1-8p) + 8p
8 - 64p + 8p
8 - 56p
8 = 56p
1/7 = p
        
                    
             
        
        
        
First off, let's convert the percentages to decimal format, so our 77% turns to 77/100 or 0.77, and our 55% turns to 55/100 or 0.55 and so on
now, the sum of both salines, must add up to the 77% mixture, let's say is "y"
so, 11 + 4 = y, and whatever the concentration level is, must also sum up to the mixture's concentration of 77%
anyway   thus

solve for "x"
