What is the required number of points for grade A?
The number of points the student needs to have to make grade A is the student's current points of 371 plus the 7 points remaining to make grade A
Total points for A=371+7
total points for grade A=378
90% of the course total=378
divide both sides 90
90% /90 =378/90
1%=378/90
100%=378/90*100
100%=420
