Question 696316: If I had 100% going into an exam worth 30% and I came out with my mark being a 70.98, what percentage did I get on my exam?

x*0.3 + 0.7*1 = 0.7098
0.3x + 0.7 = 0.7098
0.3x = 0.7098 - 0.7
0.3x = 0.0098
x = 0.0098/0.3
x = 0.03266666666667
So you got a 3.2667% score on the exam. So it's almost like you never took the exam at all (since it's so close to 0%)
