Mix a solution that is 30% alcohol with a solution that is 80% alcohol to make 800mL of a solution that is 60% alcohol. How much of each solution should you use?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of 30% solution, since the total amt is 800 ml, then
\n" ); document.write( "(800-x) = amt of 80% solution.
\n" ); document.write( ":
\n" ); document.write( "Convert % to decimal and write an equation:
\n" ); document.write( ":
\n" ); document.write( ".30(x) + .80(800-x) = .60(800)
\n" ); document.write( ":
\n" ); document.write( ".3x + 640 - .8x = 480
\n" ); document.write( ".3x - .8x = 480 - 640
\n" ); document.write( "-.5x = -160
\n" ); document.write( "x = -160/-.5
\n" ); document.write( "x = + 320 ml of the 30% solution
\n" ); document.write( ":
\n" ); document.write( "Find the amt of the 80% solution required; 800 - 320 = 480 ml
\n" ); document.write( ":
\n" ); document.write( "Check: .3(320) + .8(480) = .6(800) \n" ); document.write( "
\n" );
