To find the average, we'll sum up all the monthly changes and divide it by the number of months. Summing all the numbers, we get –30 + (–15) + 55 + 40 + (-20) + (-45) + (-10) + 65 = 40.
The number of months is 8. So dividing it by 8, we get
40/8 = 5
So the average monthly change in Timothy's savings account balance is $5.
