Respuesta :
The principle amount of $140 invested at a 6% rate of interest compounded monthly be worth after 15 years will be $340.
What is compound interest?
Compound interests are those interests where the principle amount always going to change.
For example, if you give $100 to anyone with 5% interest monthly then at the end of your month your value becomes $105 and this will become the principal amount.
Given that the principal amount is $140
P = $140
The rate of interest is 6%
r = 6%
Number of time period 15 years
t = 15
Now by compounding interest formula
A = [tex][1+r/100]^{t}[/tex]
By putting all value we get
A = [tex][1 + 6/100]^{15}[/tex]
A = $340 hence, $340 will be the total amount after 15 years.
