# Using the Midpoint Formula of Price Elasticity of Supply

Currently, at a price of \$1 each, 100 popsicles are sold per day in the perpetually hot town of Rostin. Consider the elasticity of supply. In the short run, a price increase from \$1 to \$2 is unit-elastic (Es=1.0). So how many popsicles will be sold each day in the short run if the price rises to \$2 each? In the long run, if the price rises to \$2 each? (Hint: Apply the midpoint approach to the elasticity of supply).
