Let t be the number of hours Ken worked as a tutor this month.
\n" ); document.write( "Then he earned 9t dollars for that.
\n" ); document.write( "Then 88-t is the number of hours worked as a waiter.
\n" ); document.write( "He earned 7(88-t) dollars for that.
\n" ); document.write( "Total is 9t + 7(88-t) = 9t + 616 - 7t = 2t + 616 dollars
\n" ); document.write( "
\n" );
