.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?

**MathMate**, Wednesday, September 9, 2009 at 11:55pmAssuming 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?
