Answer 1

Using compound interest, it is found that $20,581.36 will be in the account in 5 years.

What is compound interest?

The amount of money earned, in compound interest, after t years, is given by:

$A(t) = P\left(1 + \frac{r}{n}\right)^{nt}$

In which:

• A(t) is the amount of money after t years.

• P is the principal(the initial sum of money).

• r is the interest rate(as a decimal value).

• n is the number of times that interest is compounded per year.

• t is the time in years for which the money is invested or borrowed.

In this problem:

• The initial deposit is of P = 19000.

• The rate is of r = 0.016.

• Monthly compounding, hence n = 12.

• 5 years, hence t = 5.

Then:

$A(t) = P\left(1 + \frac{r}{n}\right)^{nt}$

$A(5) = 19000\left(1 + \frac{0.016}{12}\right)^{12(5)}$

$A(5) = 20581.36$

$20,581.36 will be in the account in 5 years.
