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
