$\"24%2A.25+=+6\"$ dollars
\n" ); document.write( " $\"12%2A.25+=+3\"$ dollars
\n" ); document.write( "There can't be 12 quarters, since the 75 cents
\n" ); document.write( "left over isn't evenly divided by 10
\n" ); document.write( "-----------------
\n" ); document.write( "Suppose there are 11 quarters
\n" ); document.write( " $\"+11%2A.25+=+2.75+\"$
\n" ); document.write( " $\"3.75+-+2.75+=+1\"$ dollar left
\n" ); document.write( " $\"1%2F.1+=+10\"$ dimes
\n" ); document.write( "That makes 21 coins- not enough
\n" ); document.write( "----------------
\n" ); document.write( "Suppose ther are 9 quarters
\n" ); document.write( " $\"+9%2A.25+=+2.25+\"$
\n" ); document.write( " $\"3.75+-+2.25+=+1.5\"$ dollars
\n" ); document.write( " $\"1.5%2F.1+=+15\"$ dimes
\n" ); document.write( " $\"9+%2B+15+=+24\"$
\n" ); document.write( "So, there are 9 quarters and 15 dimes
\n" ); document.write( " \n" ); document.write( "
