In planning for a new item,a manufacturer assumes that the number of items produced x and the cost in dollars C of producing these items are related by a linear equation. Projections are that 100 items will cost$10,000 to produce and that 300 items will cost $22,000 to produce.
\n" ); document.write( "Find the equation that relates C and x
\n" ); document.write( "LET C=AX+B..WHICH IS THE GENERAL FORM OF A LINEAR EQN...........
\n" ); document.write( "WE HAVE WHEN X=100....C=10000..AND WHEN X=300....C=22000....SO
\n" ); document.write( "10000=100A+B...........I
\n" ); document.write( "22000=300A+B..........II
\n" ); document.write( "EQN.II-EQN.I
\n" ); document.write( "12000=200A
\n" ); document.write( "A=60
\n" ); document.write( "10000=60*100+B
\n" ); document.write( "B=4000
\n" ); document.write( "HENCE
\n" ); document.write( "C=60X+4000 \n" ); document.write( "
