Question

Why does Joe's demand curve have a negative slope? Joe only has so much money; when other things get more expensive he must buy less coffee. Joe doesn't get the same happiness from drinking more and more coffee. He needs the price of coffee to go down to convince him to buy more. Joe is more interested in quality than quantity. He’s happy to pay more for coffee and not drink as much.

Answer 1

The answer is: He needs the price of coffee to go down to convince him to buy more.

Step-by-step explanation:

A demand curve (almost) always has a negative slope. As a product gets more expensive, the amount of people willing to buy that product decreases. So if the product gets cheaper, the more people are willing to purchase it.

The opposite happens with the supply curve, as the price of a product increases, the more companies are willing to sell that product.
