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 a decimal

The annual interest rate $r = 2%=0.02$, $P = 400$, and $t = 5$.

Step3: Substitute the values into the formula

$I=400\times0.02\times5$. First, $400\times0.02 = 8$, then $8\times5=40$.

Answer:

$40$
