<PRE><B>Question 816253</B>
g = ( (75/100)(0.60) + (100/100)(0.15) + (f/100)(0.25) ) * 100
g = A + (0.25)f
---
A = (75)(0.60) + (100)(0.15)
you do the math
---
f is your score in the final test, between 0 and 100
g is your grade for the class, between 0 and 100
---
if you know what grade you need to pass the class, substitute that for g and solve for f
