Helppppp pleaseeeeee!!!!!’

Answer 1

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

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}`
