5 cent piece= $ $\"0.05+\"$
\n" ); document.write( "10 cents piece= $ $\"0.10\"$
\n" ); document.write( " ninety nine 10 cents pieces = $ $\"99%2A0.10\"$ =$ $\"+9.9\"$ \r
\n" ); document.write( "\n" ); document.write( "let number of 5 cent pieces be $\"n\"$ , and to make $ $\"10\"$ you need\r
\n" ); document.write( "\n" ); document.write( " $\"n%2A0.05%2B99%2A0.10=10\"$ .......solve for $\"n\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"n%2A0.05%2B9.9=10\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"n%2A0.05=10-9.9\"$
\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( " $\"n%2A0.05=0.10\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"n=0.10%2F0.05\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"n=10%2F5\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"n=2\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, you will need $\"2\"$ 5 cent pieces\r
