Answer:
768
Step-by-step explanation:
This is an example of what is sometimes called the multiplication principle.
If some process consists of choosing items in a given number of ways, the number of ways of making all the choices in sequence is found by multiplication.
8 choices of pants x 3 choices of shirt x 8 choices of sweater/hoodie x 4 choices of shoes.
8 x 3 x 8 x 4 = 768 ways to choose an outfit!
