Answer:
There are 126 different pizzas that could be ordered. Letter A
Step-by-step explanation:
There are three options for the pizza:
- The type of crust
- The different toppings
- The different sizes
So we have
O1 - O2 - O3
Where O1 is the type of crust, O2 are the different toppings and O3 are the different sizes.
For each type of crust, there 7 different toppings. For each different topping, there are 6 different sizes. There are 3 types of crust.
So, in all, there are:
3*7*6 = 126 different pizzas that could be ordered. Letter A
