A local food vender can make tacos out of corn or flour tortillas, 5 different types of meat, and with or without onions. How many different tacos are possible?

20 different types of tacos

Step-by-step explanation:

We are told in the question:

A local food vender can make tacos out of corn or flour tortillas, 5 different types of meat, and with or without onions.

Hence

Types of tortillas = 2

Types of meat = 5

Onions styles = 2(with or without)

Using the fundamental principle of counting, the different types of tacos that are possible are:

2 types of tortillas × 5 different types of Meat × 2 options of onions

= 2 × 5 × 2

= 20 different types of tacos
