First, let's figure out how many cups of cheese we need for one dozen people.
There are 12 people in one dozen.
3 cups of cheese = x cups of cheese
6 people 12 people
that means we will need 6 cups of cheese for 12 people, or one dozen.
However, we want to make nachos for two dozen people.
6 cups of cheese for one dozen x 2 dozen = 12 cups of cheese
You need 12 cups of cheese to make nachos for two dozen people.
