In preparation for the new season, a local junior soccer club attempts to predict the number of children that will register to play soccer at different prices. The club believes that at a price of $162.24 per child, 90 children will register to play soccer. Additionally, at a price of $85.73 per child, it is believed that 130 children will register to play soccer. It cannot be assumed that the demand curve is linear. Calculate the midpoint price elasticity of demand for soccer registrations. Round your answer to the nearest two decimal places, giving a positive value for elasticity.
