I think not sure
Rate of change = change of amount in account/change of amount in time
800-1050/2-9=-250/-7 negatives cancel =$35.71
However $35.71x7+800=1049.97 so does the problem ask to round?

The initial balance on September 1, 2008, is $1,050.
The ending balance on March 31, 2009, is $800.
To find the difference, we subtract the ending balance from the initial balance: $1,050 - $800 = $250.
Next, we need to determine the number of months in the period. From September 1, 2008, to March 31, 2009, there are seven months.
Finally, to calculate the monthly rate of change, we divide the difference in account balance by the number of months: $250 / 7 = $35.71 (rounded to two decimal places).
Therefore, the monthly rate of change for the student's checking account over the period September 1, 2008, through March 31, 2009, is approximately $35.71.
