Let $\"+y+\"$ = total value in dollars
\n" ); document.write( "Let $\"+x+\"$ = number of each type of coin
\n" ); document.write( " $\"+y+=+.05x+%2B+.1x+%2B+.25x+\"$
\n" ); document.write( " $\"+y+=+.4x+\"$
\n" ); document.write( "----------------
\n" ); document.write( "check:
\n" ); document.write( "suppose the are $\"+10+\"$ of each type
\n" ); document.write( "of coin
\n" ); document.write( " $\"+y+=+.05%2A10+%2B+.1%2A10+%2B+.25%2A10+\"$
\n" ); document.write( " $\"+y+=+.5+%2B+1+%2B+2.5+\"$
\n" ); document.write( " $\"+y+=+4+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+y+=+.4x+\"$
\n" ); document.write( " $\"+y+=+.4%2A10+\"$
\n" ); document.write( " $\"+y+=+4+\"$
\n" ); document.write( "OK \n" ); document.write( "
