Help?? pls c:
_______

Answer 1

The answer is D. 89%

Answer 2

D. 89%

Explanation:

To calculate the average, we need to add all the grades together and divide by 4. So, we can plug in each number to find which one will give us 80%. So, if we plug in 89, and add it to 82, 75, and 75, we get 320. Then, divide it by 4, which gives us 80, and our desired average.
