The sub shop has 7 different kinds of bread, 5 types of cheese, 5 types of meat, 4 vegetable toppings and 9 types of sauce. Assuming you will pick exactly one of each how many different possibilities are there?
To find the total number of possibilities, we just need to multiply together the number of options for each category:
7 types of bread * 5 types of cheese * 5 types of meat * 4 vegetable toppings * 9 types of sauce = 7 * 5 * 5 * 4 * 9 = 2,520
So, there are 2,520 different possible combinations at the sub shop.
