The average of 87, 75, and 90 is 84. This is because if you add them all up you get 252 and divide it by 3 since there are 3 numbers, and you'll get 84.
First you would have to add all three scores together and get 252. Next you have to divide by how much numbers you have which is 3. So 252/3 is 84.
The correct answer: 84%
