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?

I think not sure
Rate of change = change of amount in account/change of amount in time
8001050/29=250/7 negatives cancel =$35.71
However $35.71x7+800=1049.97 so does the problem ask to round?
