Problem
Andy loves Krispy Kreme donuts, but realizes that the price of a glaze donut increased from $1.20 to $1.50. However, he see's an ad from Dunkin Donuts advertising a sale price of its glaze donut from $1.10 to $0.99. He plans to purchase an additional donut from Dunkin Donuts from 2 to 3. What is the Dunkin Donuts price elasticity of demand? What is the Krispy Kreme price elasticity of demand? What is the cross price elasticity of demand for a Krispy Kreme Donut?
