Algebra.Com's Answer #651304 by jorel555(1290)![]() ![]() ![]() You can put this solution on YOUR website! Let n be the amount of 50% solution. Then: \n" ); document.write( "n(.50)+(8-n)(.20)=8(.3) \n" ); document.write( ".5n-.2n+1.6=2.4 \n" ); document.write( ".3n=.8 \n" ); document.write( "n=.8/.3=2.67 pints of 50% solution; 5.33 pints of 20% solution!!!!!!!!!!!!! \n" ); document.write( " |
