In 2015, the rock and roll hall of fame and museum charged adults $25.85 for admission. seniors (65 years and older) and military personnel were charged $20.50, and children between 9 and 12 years old were charged $16.25.
using the admission fees as a guide, rank these groups based on their elasticities of demand from most to least elastic.

Explanation:

Price elasticity of demand is a measure of the sensitivity of demand for a good or service to changes in the price of that product. We say that the price elasticity of demand is elastic when a percentage change in the price of this good has major impacts on demand. On the contrary, we say that the price elasticity of demand is inelastic when variations in the price of goods have little or no influence on demand.

Thus, f firms tend to charge a lower price from the group whose demand is most price elastic (sensitive). In this case, children ages 9 to 12 who pay $ 16.25 for the ticket. The second group, whose demand is less elastic than the group of children, but more elastic than ordinary tickets is the elderly and military group, whose price is $ 20.5. Finally, the group whose demand is least price elastic is the group of ordinary adults who are willing to pay a higher price ($ 25.8).

the words "interested" and "interesting" are in the same word group as they are based in the noun "interest". however, their meanings are very different.

"interesting" is an active adjective, meaning that it causes interest.

"interested" is a passive adjective, meaning that it has interest for something.

a clear example can be "i am interested in this book, the book is really interesting."

generally speaking, an active adjective can end in -ing, and those will be adjectives causing a reaction or emotion. other examples of active adjectives are: boring, exciting, annoying, exhausting.

a passive adjective may end in -ed, and those will be describing the noun that is receiving the action. other examples of passive adjectives are: bored, excited, annoyed, exhausted.
