Answer 1

A=4,000×(1+0.06÷12)^(12×2)
A=4,508.64

Answer 2

Answer:

The amount of the withdrawal after 2 years will be $ 4508.64

Step-by-step explanation:

Given : Doris put $ 4000 in a 2-year CD paying 6% interest, compounded monthly.          

We have to find the amount of the withdrawal.

Since given the principal amount is $ 4000 for 2 years  and

Rate is 6% = 0.06  

Since, interest is calculated compounded monthly

so monthly interest rate is $\frac{6}{1200}$

Using Formula for compound interest

$A=P(1+r)^n$

Where A is amount

r is interest rate

n is time period

Substitute, we have,

$A=4000\left(1+\frac{6}{1200}\right)^{\left(12\cdot2\right)}$

Simplify, we have ,

A = 4508.64

Thus, The amount of the withdrawal after 2 years will be $ 4508.64
