All right, we have been given a situation where our friend has an 81 % average before the final exam in the course.
00:08
And we know that our final exam counts for 30 % of our grade.
00:13
We want to know what is the maximum grade that we can earn.
00:17
So if we take a look at this, if our final exam counts 70, then 81 % is 70 % of our final grade.
00:26
Which means our coursework times 70 % plus our final grade times 30 % is going to be our final grade.
00:44
That's how we're calculating.
00:48
So the best that we can do, the assumption here is make a perfect score to earn all 30 points from this.
00:56
So our coursework is an 81 times 0 .7 plus 0 .30, i'm sorry, plus 30, will give us our max final grade here.
