Question

Aaron's average score on the first 4 tests was 86. His average score on the next two tests was 92. What was Aaron's average score on all 6 tests?

Answer 1

`88`

Explanation:

Since the average score was `86` on his first four tests, that must mean that the total score he earned on the first four is:

`86*4=344`

Next, we know that the next two tests' average score was `92`, so he must have earned a total of:

`92*2=184`

So, in a total of `4+2=6` tests, his total score is:

`344+184=528`

And so, the average score is:

`528-:6=88`
