Answer 1

Answer:

$\text{(a) }\ 10,080,\\\text{(b) }\ 11,289.60,$

Step-by-step explanation:

Since interest is compounded annually, the amount of money the account has after $n$ years is given by $y=9,000\cdot 1.12^n$.

(a) After 1 year, $n=1$:

$9,000\cdot 1.12^1=\boxed{\ 10,080}$

(b) After 2 years, $n=2$:

$9,000\cdot 1.12^2=\boxed{\ 11,289.60}$
