Question 951585: For a certain student, the average of seven test scores is 80. If the two lowest scores are dropped, the average is 82. What is the average of the two lowest scores. Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! We are given
x/7 = 80, therefore x = 560
(x-y) / 5 = 82
x-y = 410
560-y = 410
y = 150
average of the two lowest scores = 150 / 2 = 75
