After weighing all but one of her children, Noni realized that if her last child weighed 94pounds, her children’s average weight would be 85 pounds. If, however, her last child had weighed 58 pounds, then this average would be only 81 pounds. How many children did Noni have?

Let N  be the number of children

 

The total weight of the children in the first case - 94 lbs = the total weight of the children in the  second case - 58 lbs

 

85N   - 94  =   81N - 58

 

4N =  94  - 58

 

4N  = 36

 

N =  9
