Answer:

95

Step-by-step explanation:

To find the average you would add all the scores up and divide by the number of scores you have, so you would do 90+100+99+91 and get 380. Then divide by 4 to get 95.

Muhaha

Answer:

100

90+100+99+91 = 380

after that divide the answer (380) by 4 and you get 95.

The reason why you divide by 4 is because there was four numbers that you had to sum up to get 380.

The answer is 100 if you round up!
