The estimate is pretty close to the exact answer, but the exact answer is better. When dealing with money, it's always a good idea to know the correct amount down to the nearest penny. Otherwise debts might pile up, expenses may get out of hand, or other bad things might happen.

In any event, both figures are below $500 so they didn't make their goal.
