You can put this solution on YOUR website!
Let $\"+w+\"$ = liters of water to be added
\n" ); document.write( " $\"+.24%2A15+=+3.6+\"$ liters of acid in 24% solution
\n" ); document.write( " $\"+3.6+%2F+%28+w+%2B+15+%29+=+.08+\"$
\n" ); document.write( " $\"+3.6+=+.08%2A%28+w+%2B+15+%29+\"$
\n" ); document.write( " $\"+3.6+=+.08w+%2B+1.2+\"$
\n" ); document.write( " $\"+.08w+=+3.6+-+1.2+\"$
\n" ); document.write( " $\"+.08w+=+2.4+\"$
\n" ); document.write( " $\"+w+=+30+\"$
\n" ); document.write( "30 liters of water should be added
\n" ); document.write( "check:
\n" ); document.write( " $\"+3.6+%2F+%28+30+%2B+15+%29+=+.08+\"$
\n" ); document.write( " $\"+3.6+%2F+45+=+.08+\"$
\n" ); document.write( " $\"+3.6+=+.08%2A45+\"$
\n" ); document.write( " $\"+3.6+=+3.6+\"$
\n" ); document.write( "OK \n" ); document.write( "
