Answer:

Step-by-step explanation:

We need to find what number he got on the test.

We know he got a bigger number than 88.

79+85+86+88+91+93+x.

Let's substitute x for 94.

79+85+86+88+91+93+94/2 = 88.

Since any other number thats near 94 doesn't equal 88, we know that this is exactly the right answer.
