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.
