Answer:
The answer is: C) The minimum price sellers are willing to accept to sell an extra unit of a good.
Step-by-step explanation:
A normal supply curve should move upward from left to right. The expresses the Law of Supply: (given that all other factors remain without change) As the price of a product increases, the quantity supplied should also increase.
For example:
An ounce of gold costs right now $1,500 and 100 ounces of gold are being traded right now at that price. If a new buyer comes in and wants to buy the 101th ounce of gold, then following a normal supply curve, the new buyer would need to pay more for that extra ounce of gold, maybe $1,510.
What the supply curve shows us is that given a certain price Y, a company will be willing to sell X amount of goods. The more demand a product has (X + 1) > X, then the price Y will increase until a new balance is found.
