76(0.85) + f(0.15) = 71
NOTE: I used the low end of the C- range (71) because that's the minimum class grade you need to pass the class
---
64.6 + f(0.15) = 71
f(0.15) = 71 - 64.6
f(0.15) = 6.4
---
f = 6.4/(0.15)
f = 42.7
---
answer:
if you get 43 or more on the final you'll get a C- or above in the class
