2. Juanita and Luis Rodriguez expected the automatic withdrawal of their fuel oil bill to be more than last
month's bill of $259.85 but did not know by how much. The activity on their account showed a previous
balance of $528.76, checks processed of $416.79, an automatic deposit of $400.00, and interest earned of
$3.56. If their new balance was $228.58, by how much did this month's fuel oil bill exceed last month's bill?
