Answer

Explanation:

Step1: Identify the simple - interest formula

The simple - interest formula is $I = Prt$, where $I$ is the interest, $P$ is the principal amount, $r$ is the annual interest rate (in decimal form), and $t$ is the time in years.

Step2: Convert the interest rate to decimal

The annual interest rate $r = 5%=0.05$. The principal amount $P = 3000$ and the time $t = 4$ years.

Step3: Substitute the values into the formula

$I=Prt=3000\times0.05\times4$. First, calculate $3000\times0.05 = 150$. Then, $150\times4=600$.

Answer:

600
