Step-by-step explanation:
Imagine you put $100 in a savings account with a yearly interest rate of 6% .
After one year, you have 100+6=$106 . After two years, if the interest is simple , you will have 106+6=$112 (adding 6% of the original principal amount each year.) But if it is compound interest , then in the second year you will earn 6% of the new amount:
1.06×$106=$112.36
Yearly Compound Interest Formula
If you put P dollars in a savings account with an annual interest rate r , and the interest is compounded yearly, then the amount A you have after t years is given by the formula:
A=P(1+r)t
Here, P=4000 , r=0.07 , and t=5 . Substituting the values in the formula, we get:
A=4000(1+0.07)5 ≈4000(1.40255) =5610.2
Therefore, the amount after 5 years would be about $5610.20 .
