which of the following is an example of an informal economic institution?
a. tipping
b. a credit union
c. a real estate office
d. a savings and loan institution

I would say that a.tipping is the correct answer

on the one hand, all the other options are formal and require a formally written agreement between all sides, and on the other hand tipping also proceeds very informally, for example by just leaving money in a jar or on the table.

Ifeel like this means that we shouldn't just live for ourselves.also, we should respect others as well as people around us. it reveals that everyone should have equalized freedom, no matter their differences: races, cultures, skin color, etc,. we all deserve the same privileges.
