\n" ); document.write( "This month, she worked a combined total of 97 hours at her two jobs.
\n" ); document.write( "Let t be the number of hours Raina worked as a tutor this month.
\n" ); document.write( "Write an expression for the combined total dollar amount she earned this month.
\n" ); document.write( "~~~~~~~~~~~~~~~~~\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " Tutor @Theo misread the problem, so his writing is not what is required in the problem.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " I came to do the job in a way in how it SHOULD be done.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "If Raina worked a combined total 97 hours at her two jobs and worked t hours as a tutor,\r\n" );
document.write( "then she worked (97-t) hours as a waitress.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "As a tutor, she earned 7t dollars;  as a waitress, she earned 12*(97-t) dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In total, she earned  7t + 12*(97-t) dollars, combined.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  In total, Raine earned 7t + 12*(97-t) dollars.\r\n" );

\n" ); document.write( "\n" ); document.write( "In such simple problems, writing governing equations/equation is, usually, quite simple and routine task.\r
\n" ); document.write( "\n" ); document.write( "The standard mantra in doing such job is to say \" write equation as you read the problem \".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Some tutors like to present such job as complicated high intellectual heroic job, but actually it is as simple as reading the problem.\r
\n" ); document.write( "\n" ); document.write( "It only requires attention while reading and a bit of common sense.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The student's goal is to learn on writing such equations AUTOMATICALLY.\r
