Answer:
Her answer is not reasonable. Her average is 83.
Step-by-step explanation:
Add all of her test grades together (96+82+78+76=332)
To find the average, you need to add all test grades she got and then divide the sum by the total number of numbers added (in this case, we added 4 tests together, so we need to divide by 4)
So she added wrong and forgot to divide by the total number of tests.
