Answer

Answer:

A. principal

Explanation:

Step1: Recall simple - interest formula

The formula for simple interest is $I = Prt$, where $I$ is the interest, $P$ is the principal amount, $r$ is the interest rate, and $t$ is the time.

Step2: Analyze given information

We know $t = 6$ years and $r=3.75%=0.0375$.

Step3: Determine missing variable

To find $I$, we still need to know the value of $P$ (the principal).
