At least 46% is needed on the final grade

Here, we want to calculate the percentage of the final exam that should be obtained so as to score at least 70%

What we have to do here is to work with averages;

Let the value to be scored be x;


\begin{gathered} (x\text{ + 95.52)/2 }\ge\text{ 70} \\ \\ x\text{ + 95.52 }\ge\text{ 2(70)} \\ \\ x\text{ + 95.52 }\ge\text{ 140} \\ \\ x\text{ }\ge\text{ 44.48} \end{gathered}

Since each question worths 2% , a score of at least 46% (23 out of 50) would give the passing grade of 70%
