Answer:
5 months
ROI = 3.75 %
Step-by-step explanation:
Since,
The simple interest formula,
Where,
P = Principal amount,
r = rate per period ( in decimal )
t = number of periods,
Here, P = 800, r = 9% = 0.09,
If A is the future amount,
We have, A = 830
I = A - P = 830 - 800 = 30
By substituting the values in the above formula,
Hence, it will take 5 months. ( 1 year = 12 months )

Answer:
$9,399.20
Step-by-step explanation:
multiply the original amount by the percentage
6,200*4.3=26,660
Then divide 26,660 by 100
26,660/100= 266.6
Multiply 266.6 by 12
266.6*12=3199.2
<u>So, $3,199.20 were added to your account over 12 years </u>
Add $3,199.20 and $6,200
$3,199.20+$6,200=$9,399.20
So, after 12 years you would have $9,399.20 in your account
