The formula would be
A=p (1-r)^t

P 3400
R 0.02

Since it decreases every 20 years
From 2000 to 2040 it decreases 2 times so
T 2

A=3,400×(1−0.02)^(2)
A=3,265

It's c

Answer:

The Amount of money in the account after 20 years $22,416.

Step-by-step explanation:

Given as :

The principal deposited into account = $4000

The rate of interest = 9% compounded annually

The time period for deposit = t = 20 years

Let the amount into account after 20 years = $A

now, According to question

<u>From compound Interest method</u>

Amount = principal × $(1+\dfrac{\textrm rate}{100})^{\textrm time}$

Or, A = $4000 × $(1+\dfrac{\textrm r}{100})^{\textrm t}$

Or, A = $4000 × $(1+\dfrac{\textrm 9}{100})^{\textrm 20}$

Or, A = $4000 × $(1.09)^{20}$

or, A = $4000 × 5.604

So, The amount in account after t years = A = $22,416

Hence, The Amount of money in the account after 20 years $22,416. Answer
