A college student is looking at her monthly checking account records. On September 1, 2008, her checking account held a balance of $1,050. At the end of March 2009, her checking account held a balance of $800. What is the monthly rate of change for the studentâ€™s checking account over the period September 1, 2008 through March 31, 2009?

math 
Reiny,
I count 7 months, so
rate of change per month = (800  1050)/7
=  $35.71
balance is declining at a rate of appr $36 per month
