Can someone help me out on this problem and show work
DochEvi [55]

Answer: 4230.14

Step-by-step explanation:

The amount that the balance is multiplied by each month is

\frac{2448}{2040}=1.2.

So, after t months, the balance is 1700(1.2)^{t-1}.

Substituting in t=6, we get the balance is

1700(1.2)^{6-1}=\boxed{4230.14}, to the nearest hundredth.
