Final answer:
A Bigger Better Burger comes with lettuce, tomato, pickles, onion, cheese, bacon, and secret sauce as per option 'a'. The interpretation of the sandwich composition, similar to an equation, assists in understanding how these ingredients come together.
Step-by-step explanation:
On a Bigger Better Burger, option 'a' includes lettuce, tomato, pickles, onion, cheese, bacon, and secret sauce. Comparing to how we describe a ham sandwich, with 2 slices of ham (H), a slice of cheese (C), a slice of tomato (T), 5 pickles (P), and 2 slices of bread (B), we can see a similar approach in indicating what comes on a burger. Just as there is an equation for the sandwich make-up, one could create a similar formula for a burger's ingredients. In this case, option 'a' would look like this: Lettuce (L) + Tomato (T) + Pickles (P) + Onion (O) + Cheese (C) + Bacon (B) + Secret Sauce (S).
