You can put this solution on YOUR website!
Let \"+x+\" = ml of the 5% solution to be added
\n" ); document.write( "\"+.05x+\" = ml of the Minoxidil in 5% solution
\n" ); document.write( "\"+.01%2A100+=+1+\" ml of the Minoxidil in 1% solution
\n" ); document.write( "---------------------------------------------
\n" ); document.write( "(1) \"+x+%2B+100+\" = ml of 5% plus 1% solution
\n" ); document.write( "(2) \"+%28+.05x+%2B+1+%29+%2F+%28+x+%2B+100+%29+=+.03+\"
\n" ); document.write( "----------------------------------
\n" ); document.write( "(2) \"+.05x+%2B+1+=+.03%2A%28+x+%2B+100+%29+\"
\n" ); document.write( "(2) \"+.05x+%2B+1+=+.03x+%2B+3+\"
\n" ); document.write( "(2) \"+.02x+=+2+\"
\n" ); document.write( "(2) \"+x+=+100+\"
\n" ); document.write( "---------------
\n" ); document.write( "She needs 100 ml of the 5% solution
\n" ); document.write( "check:
