You invest $1,000 in an account with 6 % interest, compounded annually. Assume you do not touch the money or add money other tha

IRISSAK [1]

Answer:

A) 1790.85

Step-by-step explanation:

Hi there!

In order to solve this problem, you’ll need to use the compound interest formula $x = p(1 + \frac{r}{n} )^n^t$

p will be your principle, or starting amount, which is 1,000.

r will be your percentage, which is 0.06.

n will be the amount of times interest is compounded, since this question says compounded anually, your compound will be 1.

t is the time in years it is compounded, which is 10.

When the numbers are plugged in, we get $x = 1,000(1 + \frac{0.06}{1})^1^0$

When we solve for this, we get 1790.85.

Hope this helps! :)
