Answer:
<em>800 possible combinations</em>
Step-by-step explanation:
We can reach the answer by simple logic reasoning. Knowing Fizzbos' sandwiches have one type of bread, one meat, one type of cheese and one vegetable for their sandwiches, we can find the possible combinations like this:
We have 5 choices of bread, there are, of course, 5 different kinds of sandwiches to offer.
We also know there are 5 types of meat toppings which, combined with the 5 possible choices we already have, will make
5*5 possible combinations
Now we consider the 4 types of cheese combined with our previous kinds of sandwiches to get
5*5*4 possible combinations
Finally, we have 8 vegetable toppings, making our final result
5*5*4*8 = 800 possible combinations
