//http://en.wikipedia.org/wiki/Price_elasticity_of_demand

//In general, the demand for a good is said to be inelastic (or relatively inelastic) when the PED is less than one (in absolute value): 
//that is, changes in price have a relatively small effect on the quantity of the good demanded. 

//The demand for a good is said to be elastic (or relatively elastic) when its PED is greater than one (in absolute value): 
//that is, changes in price have a relatively large effect on the quantity of a good demanded.

//Revenue is maximized when price is set so that the PED is exactly one.
