Exercise 4

Danny "Dimes" Donahue is a neighborhood's 9-year old entrepreneur. His most recent venture is selling homemade brownies that he bakes himself. At a price of $1.50 each, he sellS₁00. At a price of $1.00 each, he sellS₃00. Is demand elastic or inelastic over this price range? If demand had the same elasticity for a price decline from $1.00 to $0.50 as it does for the decline from $1.50 to $1.00, would cutting the price from $1.00 to $0.50 increase or decrease Danny's total revenue?
