Answer 1

Answer:

D is the answer

Step-by-step explanation:

add all the numbers together then divide by the amount of numbers you added together to find the average of anything. so in this case just add 60 10 and 20 which gets you 90 and then you divide by 3 since you used three numbers and you get 30 and then you add your negative sign which equals -30.
