\n" ); document.write( "b) What happens to her sales every time she raises her price by $1?
\n" ); document.write( ":

\n" ); document.write( "a) $\"400%3E600-40P\"$ ----> $\"-200%3E-40P\"$ ---> $\"5%3CP\"$ or $\"P%3E5\"$
\n" ); document.write( ":
\n" ); document.write( "so the number of cans sold will be equal or more as long as the price isnt raised by more than 5 dollars any price raise above 5 will produce less cans sold
\n" ); document.write( ":
\n" ); document.write( "b)every time she raises the price by one dollar the amount of cans sold falls by 40 cans \n" ); document.write( "
