Twenty grams of solution P is 10% alcohol and 30 grams of solution is 20% alcohol by mass these two solutions are mixed together, what is the percent of alcohol in the mixture? 
:
let x = the percent of the final mixture
10(20) + 20(30) = x(20 + 30)
200 + 600 = 50x
800/50 = x
x = 16% is the final mixture
