I am not extremely sure about this but I think the amount of different pizza that can be ordered is 15. Because, they offer exactly 15 different toppings. Right? No, probably wrong:(

The answer will be:

C(15,1) + C(15,2) + C(15,3) +...+ C(15,15)

The number will be huge. My current calculator cannot compute it
