Answer

Explanation:

Step1: Find savings at month 5 and 10

From the graph, at month 5, savings is $500; at month 10, savings is $900.

Step2: Calculate the total increase

Total increase = $900 - $500 = $400.

Step3: Calculate number of months passed

Number of months from 5 to 10 is 10 - 5 = 5 months.

Step4: Calculate average increase per month

Average increase per month = $\frac{400}{5}=80$.
