The presented word problem is ambiguous... the growth could be based on a number of possible models, so we assume that the growth is linear. A linear model can be solved by using two points (8,45000) and (11,45000), using 2000 as the reference for y=0.
The model is then y=13000x-59000, which means there was an initial debt of $59,000.
