y=32x+200, the slope in this form is the number in front of x or 32, which is the rate of change per year or a positive 32000 tons per year.

\n" ); document.write( "-
\n" ); document.write( "The product is maximum when the numbers are the same, or 20. The product will be 400.
\n" ); document.write( "Similarly numbers that add up to 150 have a maximum product when the numbers are the same, or 75.
