2900 dollars is placed in an account with an annual interest rate of 9%. how much
will be in the account after 13 years, to the nearest cent?

And the value after 13 years would be $8890.83.

Step-by-step explanation:

For this case we assume that we can use the compound interest formula given by:

Where:

A= represent the future value

P = represent the present value

r= the interest rate on fraction

n= number of times that the interest is effective in a year

For this case we have the following info:

P=2900$, r= 0.09, n = 1 (since it's annual) and t =13 years

We want to find the value of A and if we replace we got:

And the value after 13 years would be $8890.83.

And the amount of interest earned would be: 8890.83-2900=$5990.833
