Sami has $500 to invest. Suppose he has the following investment options: 3% compounded annually for 4 years, 4% compounded annually for 3 years, 2.5% compounded every 2 years for 6 years, and 5% compounded annually for 2 years. Which investment will give him the most money at the end of its investment period? (Remember, the formula is A = P(1 + r)t.)

Respuesta :

Answer:

Sami should invest in 1st case, to get the maximum money.

Step-by-step explanation:

Sami has $500 to invest.

We will use the compound interest formula :

[tex]A=p(1+r/n)^{nt}[/tex]

Case 1:

p = 500

r = 3% or 0.03

t = 4

n = 1

Putting the values in formula we get,

[tex]A=500(1+0.03/1)^{4}[/tex]

[tex]A=500(1.03)^{4}[/tex]

A = $562.75

Case 2:

p = 500

r = 4% or 0.04

n = 1

t = 3

Putting the values in formula we get,

[tex]A=500(1+0.04/1)^{3}[/tex]

[tex]A=500(1.04)^{3}[/tex]

A = $562.43

Case 3:

p = 500

r = 2.5% or 0.025

n = 3

t = 6

Putting the values in formula we get,

[tex]A=500(1+0.025/3)^{6}[/tex]

[tex]A=500(1.0083)^{6}[/tex]

A = $525.42

Case 4:

p = 500

r = 5% or 0.05

n = 1

t = 2

Putting the values in formula we get,

[tex]A=500(1+0.05/1)^{2}[/tex]

[tex]A=500(1.05)^{2}[/tex]

A = $551.25

Comparing all values we can see that case 1 has the highest amount.

Hence, Sami should invest in 1st case, to get the maximum money.
