\n" ); document.write( "Since the store sold 2,500 copies and 670 copies remain unsold, then the total amount of books they had for sale was 3,170 (2,500 + 670).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since 2,500 copies out of 3,170 copies were sold, then the percent of the total copies sold is:\r
\n" ); document.write( "\n" ); document.write( "\"2500%2F3170%2A100\" = \"25000%2F317\" = \"highlight_green%2878.86%29\"%.
