Hints:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You have 30 coins, so $\"n%2Bd+=+30\"$ . You can solve for d to get $\"d+=+30-n\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The coins total in value of $2.50, so $\"0.05n%2B0.10d=2.50\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can then plug in $\"d+=+30-n\"$ to get $\"0.05n%2B0.10%2830-n%29=2.50\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solving for n gives you the number of nickels. Use that to find the number of dimes. \n" ); document.write( "
