A. Do I just add them all to make 21? Or do I mulpite them?

Answer 1

You do both addition and multiplication.

Let's start with the sets of aunt and uncles.

There are going to be 2 people in each set. One person being the aunt, the other is the uncle. To find the total number of aunts and uncles we multiply by 2.

So....

2x8 = 16

Next, we have to find the cousins. It says that there are twice as many cousins as there are uncles. There are 8 uncles so once again we multiply by 2..

2x8 = 16.

Add the grandparents and Hector's family and we get the total.

16 + 16 + 2 + 5 = ????
