First of all you need to multiply 12numbers x 54average = 648total
This is the total you need to add the other two totals to.
Now Add 65 and 85 to this.
648 + 65 + 85 = 798
Now you need to add to the 12 numbers the other two numbers which equals 14total numbers
Now your total is 798 divided by 14 = 57average
