You can put this solution on YOUR website!
I can do A and B, so I hope that helps.
\n" ); document.write( "First, A is a system of equations for the two machines. Also known as linear programming. The machine I is 2A + 1B = 180 min. and Machine II is 1A + 3B = 300, so using either matrix, substitution, or elimination.
\n" ); document.write( "2(1A + 3B = 300) is 2A + 6B = 600 subtract 2A + 1B = 180
\n" ); document.write( " 2A + 6B = 600
\n" ); document.write( "-2A - 1B = -180
\n" ); document.write( " 5B = 420
\n" ); document.write( "B = 84, then substitute B into one of the equations. 1A + 3(84) = 300
\n" ); document.write( "A = 48
\n" ); document.write( "Profit then for the company is 1(48) + 1.4(84) = 165.60\r
\n" ); document.write( "\n" ); document.write( "B) is asking if you increase the minutes for the maximum profit. Max profit would be no A and all B. because you make more money on B.
\n" ); document.write( "Since the first restraint for B is machine 1: 2(0) + B = 180, then you can only make 180 B parts because of machine 1's limits.
\n" ); document.write( "Machine 2 is 1(0) + 3B = 300 + k where 0 + 3(180) = 300 + 240 (540 min total)
\n" ); document.write( "so the range for k is
\n" ); document.write( "1 < = k < = 240\r
\n" ); document.write( "\n" ); document.write( "If I understand C correctly, the answer is 1.4 (180) = $252
\n" ); document.write( "
\n" );
