Joey is saving up for a down payment on a car. He plans to invest $2,000 at the end of every year for 3 years. If the interest rate on the account is 2.05% compounding annually, what is the present value of the investment? $4,180.20 $5,762.15 $5,891.08 $5,978.76

Respuesta :

A=Annual amount=2000
i=annual interest=0.0205
n=number of years=3
Present value
=A((1+i)^n-1)/(i(1+i)^n)
=2000(1.0205^3-1)/(.0205(1.0205^3))
=5762.15

Answer:

B. $5762.15.

Step-by-step explanation:

We have been given that Joey plans to invest $2,000 at the end of every year for 3 years. The interest rate on the account is 2.05% compounding annually.

We will use present value formula to solve our given problem.  

[tex]\text{Present value}=P*[\frac{1-(1+r)^{-n}}{r}][/tex], where,

[tex]P=\text{Periodic payment}[/tex],

[tex]r=\text{Rate per period in decimal form}[/tex],

[tex]n=\text{Number of periods}[/tex].

Let us convert our given rate in decimal form.

[tex]2.05\%=\frac{2.05}{100}=0.0205[/tex]

Upon substituting our given values in above formula we will get,

[tex]\text{Present value}=2000*[\frac{1-(1+0.0205)^{-3}}{0.0205}][/tex]

[tex]\text{Present value}=2000*[\frac{1-(1.0205)^{-3}}{0.0205}][/tex]

[tex]\text{Present value}=2000*[\frac{1-0.94093792}{0.0205}][/tex]

[tex]\text{Present value}=2000*[\frac{0.05906208}{0.0205}][/tex]

[tex]\text{Present value}=2000*2.88107688[/tex]

[tex]\text{Present value}=5762.15376\approx 5762.15[/tex]

Therefore, the present value of the investment will be $5762.15 and option B is the correct choice.
