Here's an easy way to represent it. When you talk about your dining options, you have two types of choices. A. Type of hot dogs B. Toppings on whatever hot dog is selected in "A." Therefore, you have 10 different combinations, since you have two different types of hot dogs, times five different types of toppings. Another way to represent it is to use letters for the hot dogs (B=beef, T=turkey) and numbers for the toppings. So then the combinations are B1, B2, B3, B4, B5, T1, T2, T3, T4, T5, which still gives us ten combinations.
