Consider two markets: the market for waffles and the market for pancakes. The initial equilibrium for both markets is the same, the equilibrium price is $6.50, and the equilibrium quantity is 35.0. When the price is $9.75, the quantity supplied of waffles is 57.0 and the quantity supplied of pancakes is 101.0. For simplicity of analysis, the demand for both goods is the same. Using the midpoint formula, calculate the elasticity of supply for pancakes. Please round to two decimal places. Supply in the market for waffles is
