A druggist mixes a 10% solution of iodine with a 15% solution of iodine.
\n" ); document.write( " How much of each solution should be used in order to obtain 20 cubic centimeters of a 12% solution?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of 15% solution
\n" ); document.write( "then
\n" ); document.write( "(20-x) = amt of 10% solution
\n" ); document.write( ":
\n" ); document.write( "A typical mixture equation
\n" ); document.write( ".15x + .10(20-x) = .12(20)
\n" ); document.write( ".15x + 2 - .10x = 2.4
\n" ); document.write( ".15x - .10x = 2.4 - 2
\n" ); document.write( ".05x = .4
\n" ); document.write( "x = \".4%2F.05\"
\n" ); document.write( "x = 8 cc of 15% solution required
\n" ); document.write( "then
\n" ); document.write( "20 - 8 = 12 cc of 10% solution
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check answer in original mixture equation
\n" ); document.write( ".15(8) + .10(12) = .12(20)
\n" ); document.write( "1.2 + 1.2 = 2.4
