Answer

Final Answer: The number of ways you can order a sandwich is $16$ .

Steps

Step 1 ：This is a problem of combinations. Each ingredient (ham, mustard, mayo, cheese) can be either included or not included in the sandwich. So for each ingredient, there are 2 possibilities. Since there are 4 ingredients, the total number of combinations would be $2^{4}$ .

Step 2 ：Calculate the total number of combinations: $n u m_i n g r e d i e n t s = 4$

Step 3 ：Calculate the total number of combinations: $n u m_c o m b i n a t i o n s = 2^{n u m_i n g r e d i e n t s} = 16$

Step 4 ：Final Answer: The number of ways you can order a sandwich is $16$ .
