Question 777383: The average of a set of n numbers is defined as their sum divided by n. If John had an average score of 83 on three tests, and if his first two tests had the average score of 88, what score did John receive on the thirds test?

Average score for three tests = 83
Actual total of scores = 83*3 = 249
Average score for two tests = 88
Actual total of scores = 88*2 = 176
249 - 176 = 73
This is the score that John received
on the third test.
Hope this helps.
