Answer: $ 14736 (approx)
Step-by-step explanation:
Since, Maturity value is the amount payable to an investor at the end of a holding period of debt instrument.
And, It is defined as, 
Where, P is the principal amount,
r is the interest rate
And, n is the time period.
Here, P= $4,400 r= 12 % and n = 172/365
Thus, Maturity value for this loan,

⇒V= 4400 × 3.34908932078 = 14735.9930114 ≈ 14736
8.04 * 100= 804
You move the decimal point two times to the right
8.04*101=812.04
10=5×2 or 5×2=10 or 2×5=10 or 10=2×5
they're all the same thig but i'd probably go with 5×2=10 :)
