**Reiny**, Monday, March 14, 2011 at 5:28pmif the average of 5 numbers is 28, the total of the 5 numbers is 5(28) or 140

so (140 + x)/6 = 30

times 6

140 + x = 180

x = 180-140

x = 40

notice in the 2nd, you don't have enough information.

You have to know how many tests gave Anne her average of 92
