\n" ); document.write( "
Stuffing 1,500 is regarded as 1 JOB\r\n" );
document.write( "Stuffing 750 is considered to be ½ of the JOB\r\n" );
document.write( "\r\n" );
document.write( "Let time it takes the sister to do the job by herself be S\r\n" );
document.write( "Then she can do \"1%2FS\" of job in 1 hour\r\n" );
document.write( "\r\n" );
document.write( "Kevin can do the job by himself in 4 hours\r\n" );
document.write( "So, he can do ¼ of job in 1 hour\r\n" );
document.write( "\r\n" );
document.write( "Working together, they both can do the job in 3 hours, so we the get: \"matrix%281%2C3%2C+1%2FS+%2B+1%2F4%2C+%22=%22%2C+1%2F3%29\"\r\n" );
document.write( "12 + 3S = 4S ------ Multiplying by LCD, 12S\r\n" );
document.write( "Time it takes the sister to do the job by herself, or S = 12 hours\r\n" );
document.write( "\r\n" );
document.write( "If she can do entire job (stuffing 1,500 shrimp) in 12 hours, then she can complete
