Answer: 675
m represents the time she has been paying. And B represents how much she owed. 
So to find how much she owed at the beginning, when no time had passed, we need to set m equal to zero. 
When m is zero, the equation is
B = -100(0) + 675
B= 675
So 675 is how much she owed at the beginning of the year.
