3.6 Elasticity of Demand Given a demand function D(x) (quantity, also called q) where x is the price of an item, we want to determine how a small percentage increase in price affects the demand for the item. Percent change in price: (given as a decimal) Percent change in quantity: (given as a decimal) E(x) is the negative ratio of percent change in quantity to percent change in price.

7
**For example: if a small increase in price causes a larger decrease**

in demand, this could result in a decrease in revenue. (Bad for business) In this case, E(x) would be a number > 1, and the demand is called elastic. On the other hand, a small increase in price may cause a smaller decrease in demand, resulting in an increase in revenue. Here, E(x) would be a number < 1, and the demand is called inelastic. If a percent change in price results in an equal percent change in demand, E(x) = 1, and demand is unit elastic.

8
**Calculus & Elasticity and Revenue**

Using calculus, and taking the limit as ∆x → 0, we can show that We will use this formula for elasticity to find the elasticity of demand for a given demand function D(x), and to calculate elasticity at various prices.

9
**Revenue is related to elasticity since R(x) = price * demand.**

If demand is inelastic, a small increase in price will result in an increase in revenue. If demand is elastic, a small increase in price will result in an decrease in revenue. If demand is unit elastic, the current price represents maximum revenue.
