The market demand for a gallon of mineral water is P = 10 -.05Q. The producer wants to produce where the elasticity of demandis unity. What price should she charge and what quantity should besold to achieve that goal? b. An economist calculates that theprice elasticity of demand for potatoes in Ireland was 0.80 in1980. To do her analysis, she uses consumer expenditure datadenominated in Irish pounds.
