Need help on where to start, I am lost.
Josie goes to the local submarine sandwich shop. She can choose from 21 types of sandwiches. There are three different types of cheeses, 8 types of vegetables, and seven types of sauce. Assuming that Josie only chooses 1 type of cheese, 1 vegetable and 1 sauce, how many choices does she have?
