Question: You are a manager in charge of monitoring cash flow at a company that makes photography equipment. Traditional photography equipment comprises 80 percent of your revenues, which grow about 2 percent annually. You recently received a preliminary report that suggest consumers take three times more digital photographs than photos with traditional film, and that the cross-price elasticity of demand between digital and disposable cameras is -.02. In 2009, your company earned about $400 million from sales of digital cameras and about $600 million from sales of disposable cameras. If the own price elasticity of demand for disposable camera is -2.5, how will a 1 percent decrease in the price of disposable cameras affect your overall revenues from both disposable and digital camera sales?
