strojnjashka [21]

Answer:

Step-by-step explanation:

The equation actually looks like this

V=P(1-r)^t and filling in the info given:

V=25,000(1-.2)^{4.5 which simplifies to

V=25,000(.8)^{4.5

Orders of operation tells us that we need to take care of the exponential stuff first, so

V = 25,000(.3663573) and

V = $9158.93 which rounds to what is shown as the second choice down: $9,159.
