document.write( "Question 1063765: Jack & Jill charge $23 for a custom painted water pail. They currently sell 110 water pails a month. They estimate that for each $1 decrease in the cost of the pails, they could sell 10 more pails a month. What price will maximize Jack & Jill's income? If they charges this price, how much income should they expect? \n" ); document.write( "

Look for a pattern in price, and how many pails sold.\r

document.write( "23-1        110+10\r\n" );
