Isn't your final grade figured on five tests?
0.81 * 500 = 405
405 - 323 = 82
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%?
.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
