Answer:

The average of the John scores is 84.75.

Step-by-step explanation:

Formula of average is given as :

$A=\frac{\text{Sum of all the terms}}{\text{Number of terms}}$

We have:

Test grades of John: 82, 93, 75, and 89

Number of terms - 4

Average of the score of the John;

$a=\frac{82 + 93 +75 + 89}{4}=84.75$

The average of the John scores is 84.75.

First you add all the numbers together. So you add 82+93+75+89 to get 339. Once you get that, you divide it by the amount of numbers there are. In this case, it's 4. 339 divided by 4 is 84.75.
