2. Four towns share a common water source. By buying open land along the watershed (area from which the water flows) they can preserve its purity from sewage, road runoff, etc. The land demand schedule for each town based on water treatment costs saved can be expressed as: P = $34,000 – 10 Q where Q, is acres purchased, and P is the price per acre that the town would be willing to pay. a) If the cost of land is $30,000 per acre, how much land will be purchased if each town operates independently?
