Homework Help: math

Posted by Kay on Thursday, September 10, 2009 at 8:35pm.

If you earn the grades of 81, 84, 78, 80 in four tests what should your final testís score be in order to have an average of 81%?

.81x400=324
Need a total of 324 pts
Test grades so far 81,84,78,80 = 323
324-323=1
You need at least one more point to get an 81

Can someone please check my problem to see if it is correct if not please guide me thank you
