Ad company has $24000 to spend on ads. Radio ad+ $300/30 sec, TV ad $400/30 sec
\n" ); document.write( "300x + $400y = 24000.
\n" ); document.write( " What do x and Y represent?
\n" ); document.write( "x = no. of radio ads
\n" ); document.write( "y = no. of TV ads
\n" ); document.write( ";
\n" ); document.write( " Graph the equation.
\n" ); document.write( "We want the graph in the general y= form
\n" ); document.write( "300x + $400y = 24000
\n" ); document.write( ";
\n" ); document.write( "Subtract 300x from both sides
\n" ); document.write( "400y = 2400 - 300x
\n" ); document.write( ":
\n" ); document.write( "Simplify, divide by 100
\n" ); document.write( "4y = 24 - 3x
\n" ); document.write( ":
\n" ); document.write( "Divide both sides by 4
\n" ); document.write( "y = 6 - .75x
\n" ); document.write( ":
\n" ); document.write( "Plot the graph using points x=0; y=6; and x=4; y=3
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-6%2C+10%2C+-6%2C+10%2C+6-.75x%29+\"
\n" ); document.write( ":
\n" ); document.write( "How many solutions are there to the equation?
\n" ); document.write( "There are 9 solutions for integer values for x; from 0 to 8
\n" ); document.write( ":
\n" ); document.write( " How many solutions are there to the equation given that the number of ads of each type must be a whole number?
\n" ); document.write( ":
\n" ); document.write( "If you require y to be an integer also, only 3, x=0, y=6; x=4, y=3; x=8 y=0 \n" ); document.write( "
\n" );
