Answer:

The value of B is 1.025.

Step-by-step explanation:

Given information:

Initial balance = $8000

Interest rate = 2.5% per year = 0.025

The general form of exponential function is

y=AB^x          .... (1)

where, A is initial value and B is growth factor.

It can also written as

y=A(1+r)^x       ... (2)

From (1) we get

B=1+r=1+0.025=1.025

Therefore the value of B is 1.025.
