Question 640590: David has scores of 79, 96, 63, 54 on his algebra tests. Use an inequality to find the minimum score he can make on the final exam to pass the course with an average of 70 or higher, given that the final counts as 3 tests. Answer by solver91311(24713) (Show Source):
Hint: If he needs to get a 70 average on 7 tests then he needs to score a total of 490 points for all of his tests. So 3 times what he gets on the last test plus the sum of the scores of the tests he has already taken has to be greater than or equal to 490.
