Answer 1

840 sandwich combos.

Explanation:

In these types of problems, you want to multiply everything in the problem together. In this problem you have 6 types of bread, 4 types of cheese, 7 types of protein, and 5 types of dressing. You want to take all of the usefull numbers out of the problem (sometimes in problems they throw in extra numbers to throw you off) and multiply them together. 6×4×7×5= 840
