Answer:
Based on the information supply of cards is more elastic (price sensitive) than that of roses
Explanation:
Price elasticity of supply is defined as the sensitivity of quantity supplied to changes in price.
The formula is given below
Price elasticity of supply= Change in quantity supplied ÷ Change in price
In this scenario the demand for both roses and cards increases, however the price of roses increases more.
This implies that the denominator in the formula is higher in roses resulting in smaller price elasticity of supply.
The elasticity of supply for cards is higher than that of roses, so it is more sensitive to changes in price.
Cards can be stored from year to year so the labour for maintaining a stock of cards is low with resultant low price.
On the other hand roses require care to grow. It requires watering, application of chemicals to treat infestation and so on. So suppliers tend to push the extra cost of growing roses to the buyers
