The average weight of 10 children is 88 pounds. Two more children join the group: one weighs 95 pounds and the other 93 pounds. What is the average weight for the twelve children?
-----------------
Fact: (total weight)/(total number) = average weight
-----------------
First 10 children:
total weight/10 = 88
total weight = 880
-----
Addinging 2 more children:
total weight = (880+95+93) = 1068 lbs
---
Average of 12 children = 1068/12 = 89 lbs.
