Answer:
A sandwich shop offers:
Bread: 1 , 2
Meat: 1 , 2 , 3 , 4
Cheese: 1 , 2 , 3
Choose one to be your starting point. For example, choose Bread. You only choose one of each, so:
Bread 1, Meat 1, Cheese 1
Bread 1, Meat 1, Cheese 2
Bread 1, Meat 1, Cheese 3
etc. etc.
However, note that there is an easier way to solve it. In this case, you can use the <em>Fundamental Principle of Counting</em>, which each total number of choices are added together.
Multiply them:
Bread x Meat x Cheese = 2 x 4 x 3 = 24
There are 24 different types of sandwiches that can be made if only one of each is chosen.
