Answer
The person owes $\$ 2930$ after making the first payment.
Work Step by Step
We substitute $B_0 $ into $B_n$ in order to compute $B_1$.
Therefore, $B_1=1.01 B_{1-1}-100 \\ =1.01B_0-100 \\=1.01(3000)-100\\=3030-1000 \\= \$ 2930$
We find that the person owes $\$ 2930$ after making the first payment.
