4). At diving competiotion, Jan's first dive received 9 scores that averaged 9.0. To calculate her final score for the dive, the highest and lowest scores were removed and the average was taken of the remaining seven scores. If her final score was 9.1, what was the sum of the teo removed scores?

to get an average of 9 on 9 scores, her total of all the scores must have been 81
So after the high and low are removed there were 7 scores for an average of 9.1
so that total must have been 9.1(7) = 63.7
so the sum of the two scores removes was 17.3
