Okay, so suppose that i have homework plus my exams have to add to 350 points in my class.
00:10
Okay, so i have five homework assignments and the averages i have for the homework are four, eight, plus seven, plus seven, plus nine.
00:19
So my total for the homework when i add all these together is approximately 35 points.
00:25
Plus okay, i have three exams that are worth 100 points.
00:29
So i have one exam that's 78 and then another that's 83.
00:34
And i have a third exam that i'm not sure about.
00:36
So 78 plus 83 is approximately 161 plus my third exam.
00:43
And i want to know how many points is possible to reach an a.
00:47
So what exactly is an a? well, an a is equal to or above 90%.
00:55
So of 350, 90 % of 350, i'm gonna multiply by 0 .9.
01:01
That's approximately 315 points...
