Question 818730: A student has earned 468 out of 600 points possible in a class. The final is worth 200 points. How many points must the student get on the final in order to receive 639 points total in the class? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! total points possible in class:
P = 600 + 200 = 800
---
(468/600)(600/800) + (f/200)(200/800) = (639/800)
(468/800) + (f/800) = (639/800)
f/800 = (639/800) - (468/800)
f = 639 - 468
f = 171

get 171 points on final to get class grade of 639
