Underground sells only sandwiches. They offer four choices of bread, four types of meat toppings, three types of cheese and nine vegetable toppings. If you must choose exactly one type of bread, one meat, one type of cheese and one vegetable for your sandwich, how many different kinds of sandwiches can you order at Underground?
To calculate the total number of different kinds of sandwiches, we will multiply the number of choices for each component.
Number of choices for bread: 4
Number of choices for meat: 4
Number of choices for cheese: 3
Number of choices for vegetables: 9
Total number of different kinds of sandwiches = (Number of choices for bread) x (Number of choices for meat) x (Number of choices for cheese) x (Number of choices of vegetable)
= 4 x 4 x 3 x 9
= 432
Therefore, you can order 432 different kinds of sandwiches at Underground.
