\n" ); document.write( "\n" ); document.write( "1 dime is 0.10 dollar.
\n" ); document.write( "1 penny is 0.01 dollar.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"system%28d%2Bp=100%2C0.1d%2B0.01p=7.57%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiply the money equation, both sides, by 100 to eliminate the fractions or denominators.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"system%28d%2Bp=100%2C10d%2Bp=757%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You may want to use elimination first to directly solve for d.
