The ECON3305 Company was considering a price increase and wished to estimate the price elasticity of demand. A market researcher and an economist, you and Sandy, were hired to study demand. In a controlled experiment, it was calculated that at the 8 cents, 100 pencils were sold while at 10 cents, 60 pencils were sold, yielding an elasticity of 2.25. However, Sandy and you were industrial spies, employed by the EF Pencil Co. and sent to ECON3305 to cause as much trouble as possible. So Sandy and you decided to change the base for their elasticity figure, how can determine the price in terms of dollars instead of pennies?
