A cat breeder has the following amounts of cat food: 120 units of tuna, 110 units of liver, and 70 units of chicken.
\n" ); document.write( "To raise a Siamese cat, the breeder must use 2 units of tuna, 2 of liver and 3 of chicken, while raising a Persian cat requires

\n" ); document.write( "should be raised in order to obtain maximum gross income?
\n" ); document.write( "Set up the system of equations and initial simplex tableau.

\r\n" );
document.write( "Let x = no. of Siamese cats to be raised\r\n" );
document.write( "Let y = no. of Persian cats to be raised\r\n" );
document.write( "We make the tuna inequality to make sure we don't run out of tuna,\r\n" );
document.write( "\"2x+%2B+3y+%3C=+120\"\r\n" );

document.write( "\"3x+%2B+1y+%3C=+70\"\r\n" );
document.write( "We make the objective equation for the income that we want to maximize.\r\n" );
document.write( "P = 14x + 16y\r\n" );

document.write( "\"3x+%2B+1y+%2B+s%5B3%5D++=+70\"\r\n" );
document.write( "Then we rearrange the objective equation so that the variable terms are\r\n" );
document.write( "negative and we have 0 on the right:\r\n" );
document.write( "\"-14x+-+16y+%2B+P+=+0\"\r\n" );
