if the demand of a good or service is up and supply is down the price will go up but if demand is down and supply is up prices go down
Answer: The Ninth Amendment
Explanation:
The Ninth Amendment to the Constitution of the United States of America simply has to do with the rights that the people has which were not really stated in the Bills of Rights.
Even though they're not listed, it should be noted that everyone has such rights and no one should deny the people from using the rights. An example is the right to travel.
