Final answer:
The demand between points d and e on the demand curve is inelastic with an elasticity value of 0.45, indicating a less than proportional response to price changes.
Step-by-step explanation:
The price elasticity of demand between points d and e on a demand curve represents how much the quantity demanded responds to a change in price. Given that the demand is described as inelastic in this interval and the calculated elasticity is 0.45, which is less than one, we can conclude that the demand does not change significantly with price changes.
Moreover, price elasticities of demand are usually negative because the price and quantity demanded move in opposite directions. However, we often refer to elasticity values as positive numbers by taking the absolute value.
The elasticity of demand between points D and E is 0.45, which is an amount smaller than one. This indicates that the demand is inelastic in this interval.
The answer is not provided in the options given, so none of the provided options are correct.
Price elasticities of demand are always negative since price and quantity demanded move in opposite directions on the demand curve.
