True annual interest rate (to the nearest tenth) = _____.

8.4
12.0
17.2
19.2

Respuesta :

5x12=60
(227.5x5x120)=13650
13650-9500=4150
apply formula
(2x12x4150)/((13650(60+1))=0.1196

Answer:

Annual interest rate is 8.4 %

Step-by-step explanation:

[tex]Net amount =227.5\cdot5\cdot12\\=$13650[/tex]

Now for calculating interest rate we use the formula : [tex]Amount=principle(1+rate\cdot time)\\13650=9500(1+rate\cdot 5)\\rate=0.086\\annual rate = 0.086\cdot100\\rate=8.6 \approx 8.4[/tex]

So, annual interest rate = 8.4 %
