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

Answerthe simplified expression isexplanationthe given expression is,let us deal with the bracket first.the two negatives in the parenthesis will become positive.the expression now becomes,we now expand the parenthesis to get,we group like terms to obtain,this simplifies to,
