How much money should be deposited today in an account that earns 5.5% compounded monthly so that it will accumulate to 11,000 in three years?

Answer :

Answer:

$9,330.35

Explanation:

We'll use the below compound interest formula to solve the problem;

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

Where A = the future amount = $11,000

P = the starting amount(the principal)

r = the interest rate in decimal = 5.5% = 5.5/100 = 0.055

n = number of compounding periods = 12

t = time periods = 3 years

So let's go ahead and substitute the above values into our equation;

[tex]11000=P(1+\frac{0.055}{12})^{12\ast3}[/tex]

We can then evaluate and find P;

[tex]\begin{gathered} 11000=P(1.004583)^{36} \\ 11000=P(1.178949) \\ P=\frac{11000}{1.178949} \\ \therefore P=9,330.35 \end{gathered}[/tex]

So the amount that should be deposited is $9,330.35
