Answer:
The different single-scoop ice-cream cones can you buy from this vendor=12
Step-by-step explanation:
Given that a vendor sells ice cream from a cart on the boardwalk. He offers vanilla, chocolate, strawberry, blueberry, and pistachio ice cream, served on either a waffle, sugar, or plain cone.
Different types of icecreams are 4
Types of cones are 3
For each ice cream say we can have either waffle, sugar or plain cone.
i.e. for each type of ice cream, we have 3 different cones.
Hence for 4 types of ice creams we have 3*4=12 different single scoop ice creamcones.
