Okay, so this problem asks us to define variable or define a variable, and then write an inequality for the situation of a restaurant that seats at most 172 people.
00:11
So a variable is just a symbol, usually a letter that represents a number in an equation or an inequality that we don't know.
00:22
And generally, that number can vary, or it can have multiple potential solutions, or it's something that changes.
00:30
Changes, and ultimately it's just an unknown.
00:34
So we could write it as a symbol or letter that represents an unknown number.
00:54
And in this case, the variable would be people because we don't know how many people are in the restaurant, and the number of people in the restaurant can change.
01:05
So our variable will be people, so we'll keep it easy, and we'll stick with p as a variable.
01:14
Now we have to consider that the restaurant seats at most 172 people.
01:18
So we know that 172 is going to be our upper limit of people.
01:25
And then we have to consider the inequality sign...
