Answer:
c. Trade can make everyone better off
Step-by-step explanation:
Trade between is not like a sports competition where one side wins and the other loses. In fact, the opposite is true: trade can be good for both parties, this is one of the principles of the economy. Commerce allows people to specialize in the activity they are best at, be it agriculture, sewing or construction. By trading with others, people can buy a greater variety of goods and services at a lower cost.
In the case set out in the question above, when Dee chose a landscaper to work for her, she showed that commerce can benefit everyone. That's because by hiring the landscaper, Dee has free time to use another activity she finds necessary, and by hiring the expert, Dee knows that the work done will be better than if she did it herself. When hired, the landscaper receives a salary that will be used for his livelihood and leisure. That way everyone benefits.
