If you earn the grades of 81, 84, 78, 80 in four tests what should your final test’s score be in order to have an average of 81%?
Need a total of 324 pts
Test grades so far 81,84,78,80 = 323
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
