Solution by Steps

step 2

The equation shows that the total loss of $9.00 over 2 months is being divided equally between the 2 months

step 3

Dividing the total loss by the number of months gives us the loss per month: $-9.00 \div 2 = -4.50$

step 4

Therefore, -4.50 represents the amount of money lost each month

B

Key Concept

Average rate of change

Explanation

The average rate of change is found by dividing the total change by the number of intervals over which the change occurred. In this case, it's the monthly loss in investment.
