Elastic
If the elasticity of demand for cereal is 1, this indicates unitary elasticity, meaning that the percentage change in quantity demanded will equal the percentage change in price. Therefore, if the price of cereal increases by 25 percent, the quantity demanded will decrease by 25 percent.
The quantity is decreasing.
No, the substitution effect is not always negative. It refers to the change in quantity demanded of a good when its price changes, leading consumers to substitute it with other goods. While a price increase typically results in a decrease in quantity demanded (a negative substitution effect), a price decrease can lead to an increase in quantity demanded, which can be viewed as a positive effect. Thus, the direction of the substitution effect depends on the nature of the price change.
Multiplying
If the percent of change is negative, then it is wrong.
in equilibrium
In this range of prices, the demand for the product is considered elastic. This is because the percentage change in quantity demanded (15 percent decrease) is greater than the percentage change in price (10 percent increase). An elastic demand indicates that consumers are responsive to price changes, leading to a significant drop in quantity demanded when prices rise.
Unit elastic
When the percentage change in price is equal to the percentage change in quantity demanded then demand is said to be unit elastic. There are 3 kinds of price elasticity of demand.
a change in demand is a movement along the demand curve, and a change in quantity demanded is a shift in the demand curve
The percentage change is always 100*(new-old)/old provided the old is non-negative. If the original quantity is greater than the new quantity, the percentage change will be negative - no big deal.
To determine the demand elasticity of the product, we can calculate the price elasticity of demand using the formula: elasticity = (% change in quantity demanded) / (% change in price). In this case, it would be -15% / 10% = -1.5. This indicates that the demand for the product is elastic, meaning that consumers are relatively sensitive to price changes; a 10% increase in price leads to a 15% decrease in quantity demanded.
This is called equilibrium.
To calculate the quantity demanded when the elasticity is given, you can use the formula: Quantity Demanded (Elasticity / (1 Elasticity)) (Price / Price Elasticity). This formula helps determine the change in quantity demanded based on the given elasticity and price.
it means that price is elastic. Price elastic means that a little change in the price will cause a substantial change in the quantity demanded.
inelastic
Price elasticity of demand is the responsiveness of quantity demanded of a good to a change in its price.Basically it describes how consumers react to a price change.The price elasticity of demand is calculated byPED= %Quantity demanded : % Change of Priceor in words: the percentage change in the quantity demanded divided by the percentage change in price
