6. The demand equation for a product is given by p=22-x^2/3x where p (in dollars) is the unit price of the product corresponding to x units of consumer demand.

a) Find the elasticity of demand for this product and evaluate it at x = 2.

b) Is the demand elastic, inelastic or of unit elasticity at x = 2?

c) At x = 2, if the price is decreased by 1%, by what percentage will the demand increase?
