\n" ); document.write( "As a studio photographer she can earn 8 JOD an hour. She wants to spend at least 6 hours as a studio photographer.
\n" ); document.write( "She can only work for a maximum of 20 hours a week.
\n" ); document.write( "Obtain inequalities and graph your solution to find her maximum possible weekly earnings.

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "            First,  the formulation is  OBVIOUSLY  incorrect.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "            To be correct,  it must say that  \"As a wedding photographer she can earn  10  Jordan Dinars  (JOD)  per hour\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "            Second,  to solve this problem,  you do not need to follow a standard procedure solving LP problems.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "            Common sense and a bit of mental reasoning is enough.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "She wants to earn maximum money.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "For it, she should work at the greater hour salary as long as possible: as long as the restrictions do allow.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The restrictions allow her to work 20-6 = 14 hours at the rate of 10 JOD per hour.\r\n" );
document.write( "\r\n" );
document.write( "The remaining 6 hours she wants to work at the rate of 8 JOD per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is the solution and the ANSWER to the problem:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    At given conditions, the maximum earning is  14*10 + 6*8 = 188 JOD.\r\n" );
document.write( "\r\n" );
document.write( "    It is achieved at 14 hours working at 10 JOD per hour and 6 hours working at 8 JOD per hour.\r\n" );
document.write( "

\n" ); document.write( "\n" ); document.write( "I hope that you will get much more benefits from this mental solution than from formal  LP-solution.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is the way on how this simple problem  SHOULD  BE  solved and  how it IS  EXPECTED  to be solved among reasonable people.\r
