John scored 88, 92, 96, and 96 in the first four chemistry tests of the school year. If all the tests are out of 100 and are equally weighted, what is the mean score of the four chemistry tests?

**Maps to Category 57 of the book.**

**Answer posted on 08/15/2021: Answer is 93.**

mean = sum of numbers/count of numbers.

sum of numbers = 88 + 92 + 96 + 96 = 372.

count of numbers = 4.

mean = 372/4 = 93
