Let the total numbers of problems be x
So, Total no. of problems x is 100%
Correct no. of problems on test = 76
We are given that he received a grade of 80%.
So, Correct no. of problems is 80 i.e. 80%
So,
![(x)/(76)=(100)/(80)\\x=(100)/(80) * 76\\x=95](https://img.qammunity.org/2021/formulas/mathematics/high-school/e4071624dxei314p9qsnok12de7ukekfek.png)
