the scores for a basketball team are 72, 84, 102, 73, 90 and 83. the scores for the next two matches bring the average up to 90. what was the total score of these two games?
You just have to figure out what 90•8 is and subtract the sum of the numbers you were given because you will now have eight numbers instead of six and that is your total sum because whatever the sum is divided by the number of terms (8) has to equal 90
