There are 12 people in mrs. hilt's living room. 6 people are wearing socks and 4 people wearing shoes. 3 people are wearing both. how many people are bare feet?

5 of them are bare feet.

Step-by-step explanation:

The data that we have is:

We have 12 people.

6 of those are wearing socks.

4 are wearing shoes.

3 are wearing both.

Then. the total number of people with something in their feet is:

the 6 wearing socks + 4 wearing shoes - 3 that use both (because those  3 are included in the 6 wearing socks and in the 4 wearing shoes, so we are counting those 3 people two times, then we need to subtract 3)

N = 6 + 4 - 3 = 6 + 1 = 7

Then the people that do not use anything in their feet is equal to:

12 - 7 = 5

2500
