Question 882958: I have a 86% in my class, my exam was worth 20% of my final mark and I got 85% on it. What's my final mark?

If your exam is worth 20% of your final mark, that means that your grade average of 86% is worth the remaining 80% of your grade. SO
86(0.80)=68.8
and
85(0.20)=17.0
add the two together and you get 85.8
Therefore your final mark is 85.8%
