Question 515521: I need help with this math problem. Anne earned an 85,90 and 95 on her first three tests. If she wants to get an A average (91 or above) what scores can she get on her fourth test to ensure that she gets an A? Then I have to write,solve and graph an inequality to represent her possible scores for the fourth test? Any help would be greatly appreciated! :)

-------------------------
Equation:
Solve: (85+90+95 + x)/4 >= 91
----
(85 + 90 + 95 + x) > = 364
----------------------------------
x >= 365-270
--
x >= 95
