Answer: 24 ways people can stand in a line
Step-by-step explanation: In this problem we're asked how many ways can 4 people stand in a line for movie tickets.
Let's start by drawing 5=4 blanks to represent the 4 different positions in the line.
Now, we know that 4 different people can fill the spot in the first position. However, once the first position is filled, only 3 people can fill the second spot and once the second spot is filled, only 2 people can fill the third spot and so on.
Now based on the counting principal, we will multiply these numbers together to find out how many ways these 4 people can stand in a line.
