The answer is:
- a new haircut
- a new car for personal use
Consumption refers to the acts that use up the resource that we had to obtain a product or services , while production refers to the act of creating the product or services.
When we get a new haircut, we use up the value of our money (resources) in exchange for the haircut (services). Buying a car for personal use also considered as investments since we are not using it to gain any profit.
