Answer 1

the answer is 88.8% how i got it is by:

30-18= 12 which is the number of member that had an average of 84
then multiply  12 times 84 = 1008 (keep this number)

last you multiply 18 by 92 which equals 1656 

add 1008 and 1656 together  and get 2664.

divide 2664 / 30 and you get the average of 88.8
