Answer:
The correct answer is: the supply of the greeting cards is less elastic than the one of the roses.
Step-by-step explanation:
To begin with, the elasticity show how much the price and the quantity are related by indicating the variation that happens to one of them when the other changes. Therefore that the supply of the greeting cards is less sensitive to price because when the quantity demanded increased the price did not change as much as the roses due to the fact that the sellers were not encourage as much as the sellers of the roses to produce more and therefore to increase the price of the cards. So to sum up, when the price changed the sellers were not encourage to increase the production of the cards as much as the production of the roses because of its elasticity.
