If x = (5y - 1), then: 4(5y - 1) - 4 = 12 (20y - 4) - 4 = 12 20y - 4 = 16 20y = 20 y = 20/20 y = 1

Question:

Define the concept of price elasticity of demand.

Inactive
Timothy A.

Price elasticity of demand refers to the responsiveness, in demand, to a change in price. Change in demand in response to a change in price indicates elasticity, while no change in demand in response to a change in price is referred to as inelasticity. In equation form, it is the percent change in quantity demanded divided by the percent change in price. A price elasticity of demand equal to zero means a product or service is perfectly inelastic (changes in price do not affect demand) , while a price elasticity greater than one means a product or service is perfectly elastic (demand is greatly affected by price).
