Question 1046331: Lucy is taken for tests in math class and has an average of 85.
a. What's score would you have to get on her fifth test to have an average of 88?
b. Can she get an average of 90? Explain. Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! a.5 x 88=440
4 x 85=340
440-340=100 needed on her fifth test to average 8 for all her tests.
b. No. Not unless she can score more than 100 on her fifth test; she would not have enough total points to average 90 on all her tests. ☺☺☺☺
