Use I = PRT to solve. (time in years)
vivado [14]

Simple interest is $ 9

<em><u>Solution:</u></em>

Given that,

P = $ 400

R = 9 \% = \frac{9}{100} = 0.09

T = 0.25 years

<em><u>The formula for simple interest is:</u></em>

I = P \times R \times T

Where,

I is the simple interest earned

R is the rate of interest in decimal

T is the number of years

<em><u>Substituting the values we get,</u></em>

I = 400 \times 0.09 \times 0.25\\\\I = 36 \times 0.25\\\\I = 9

Thus simple interest is $ 9
