Answer: 
$9,236.71 
Explanation: 
The computation of the maturity value of the note is shown below:- 
Interest Amount = ($9000 × 8%) × 120 ÷ 365 
= $720 × 120 ÷ 365 
= $236.71 
So, the Maturity Value is 
= Face value + Interest amount 
= $9,000 + $236.71 
= $9,236.71 
Therefore for computing the maturity value we simply applied the above formula.
