Assuming the final test has the same weight as the other four, then total points you need will be 500*0.81=405.
How many points do you need in the final test if the cumulative total is 323?
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 in order to have an average of 81%
is this correct?
