Question

For the first two essays you received scores of 95 and 83 what will you need to receive on the third essay for an average of an 85

Answer 1

The score for the first two essays are 95 and 83.

Let the score in third essay be x.

The average is 85.

Therefore,

`\begin{gathered} (95+83+x)/(3)=85 \\ 178+x=255 \\ x=255-178 \\ x=77 \end{gathered}`

So, the score in third essay will be 77.
