what is the simply interest. principal $ 300, rate 6.8 % time half a year 6 months
The formula for simple interest for months is I=P (r / m) n. Where P is the principle and r is rate and m is the year or 12 months and n equals how many months.
I=300 (0.068 / 12) 6 = 10.2
So the interest would be $10.2
I=PRT
I=interst
P=principal
R=rate
T=time in years
I=?
P=300
R=0.068
T=0.5
I=(300)(0.068)(0.5)
I=10.2
interest is $10.2
