How much more interest is earned on an investment of $12,585 at 3.5% interest over 5 years if the interest is compounded annually rather than earning simple interest?

Respuesta :

Answer:  $ 159.6572

Step-by-step explanation:

Here, the principal amount = $ 12,585

Annual rate of percent = 3.5 %

Time = 5 years

Thus, the simple interest for 5 years in this amount,

[tex]I_1= \frac{12585\times 3.5\times 5}{100}[/tex]

[tex]I_1= \frac{220237.5}{100}[/tex]

[tex]I_1=2202.375[/tex]

While the compound interest for 5 years in this amount,

[tex]I_2=12585(1+\frac{3.5}{100})^5-12585[/tex]

[tex]I_2=12585(1+0.035)^5-12585[/tex]

[tex]I_2=12585(1.035)^5-12585[/tex]

[tex]I_2=12585(1.18768631)-12585[/tex]

[tex]I_2=14947.0322-12585=2362.0322[/tex]

Hence, the required difference,

[tex]I_2-I_1=2362.0322-2202.375=159.6572[/tex]

Thus, he will get $ 159.6572 more compound interest rather than simple interest.
