If it is incorrect,we will have to work out,
$2000 is invested each year, so P = 2000.
r is the interest rate, which is given as 10%. Thus, r = 10
We need to find the balance due after 10 years, so t = 10.
Hence, the balance due will be
r is the interest rate, which is given as 8%. Thus, r = 8
We need to find the balance =15400
