When the highest and lowest scores were eliminated, the average number of baskets for the remaining 8 players was 79.
The eight players averaged 79 baskets each, for a total of 632 baskets.
The other two players made a total of 750 - 632 = 118 baskets. This is the sum of the highest number, which obviously must be 80 or above, and the lowest number.
