Total cost = $80.96
\n" ); document.write( "Membership fee = $1
\n" ); document.write( "So total spent on books = 80.96 - 1 = 79.96\r
\n" ); document.write( "\n" ); document.write( "Cost of each book = $19.99\r
\n" ); document.write( "\n" ); document.write( "Total number of books bought = 79.96/19.99 = 4\r
\n" ); document.write( "\n" ); document.write( "So you purchased 4 more books
