How to resolve USB port issues. Your USB ports on your Dell computer are plug and play (a plug and play device is one with a specification that facilitates the discovery of a hardware component in a computer without the need for physical device configuration or user intervention in resolving resource conflicts).
Demand elasticity is the sensitivity of the demand for a good or service due to a change in another factor. There are many factors that influence a change in demand elasticity. These factors include price, income level and availability of substitutes. One factor that can affect demand elasticity of a good or service is its price level. For example, the change in the price level for a luxury car can cause a substantial change in the quantity demanded.
Elasticity of demand = % change in quantity demanded / % change in price. It is not to be confused with the slope of the demand curve. The slope of the demand curve remains constant; however, the elasticity of the demand curve changes as you move along. The only curve that has a constant inelastic demand is a vertical demand curve. Any change in price will result in no change in quantity demanded.
