Answer:
S.I =$360
Step-by-step explanation:
Since the principal isn't visible in the question, let's assume it's $1000.
Given the following data;
Principal = $1000
Interest rate = 9%
Time = 4 months
To find the simple interest;
Mathematically, simple interest is calculated using this formula;
[tex] S.I = \frac {PRT}{100} [/tex]
Where;
S.I is simple interest.
P is the principal.
R is the interest rate.
T is the time.
Substituting into the equation, we have;
[tex] S.I = \frac {1000*9*4}{100} [/tex]
[tex] S.I = \frac {36000}{100} [/tex]
S.I =$360
Note: You should substitute the principal amount with the one given originally in the question.
