If he wants a 90% average for the four tests, the least he can afford to get on the
fourth one is 99%.
(87 + 87 + 87 + 99) / 4 = 360/4 = 90%
Good luck !
Grade average of 89 percent and 93 percent averages 91% or an A-.
If Your test grade avearge is 57 and your assignment grade is 75 and the test grade counts for 75% and asignment 25%, then your grade is .75 (57) + .25(75) = 61.5
[(100x60) + (Tx40)]/100=Average, where T is you average on the other 40% of your grade. Example: your grade average is 90 before the test. You get a 100 on the big test. [(100x60) + 90x40)]/100 = [6000 + 3600]/100 = 96
