400000 10 to the fifth power is 100000, so when you switch out the 1 for a 4, it become 400000.
The remaining 2 debts have to add up to a cetain number which I represent as x.
476.25 - 93.22 - x = 0
x = 383.03
The correct two debts should add up to -383.03.
Therefore the answer is B. -66.72 and -316.31
