Answer
Explanation:
Step1: Identify the simple - interest formula
The simple - interest formula is $I = Prt$, where $P$ is the principal amount, $r$ is the annual interest rate (in decimal form), and $t$ is the time in years.
Step2: Convert the percentage to decimal
The annual interest rate $r = 5%=0.05$, the principal amount $P = 100$, and the time $t = 3$ years.
Step3: Substitute values into the formula
$I=Prt=100\times0.05\times3$.
Step4: Calculate the interest
$100\times0.05\times3 = 15$.
