Answer:
True
Step-by-step explanation:
Demand refers to the volume of a good or service that buyers are willing and able to purchase at a certain price over a period. It means that customers should be willing to buy and have the financial ability to pay for the goods for the demand for a product to exist.
Demand for a good is affected by, among other things, customer's preferences and people's incomes. Customer preference is the willingness and the desire to get the product. People's income is the ability to pay.
