D -30 cents per week

Verified Answer :

add all the numbers together then divide by the amount of numbers you added together to find the average of anything.

For this problem you add .60+.10+.20=.90 then divide .90 by 3 because you agreed 3 numbers together. .90÷3= .30 so you are subtracting 30 cents per week or (-30)
