You can put this solution on YOUR website! Depends on the interest rate of the CD. Simple interest formula is I = p*r*t which stands for interest equals principle times interest rate times time(years) so for this problem principle equals 2000 and time equals 2.
Remember interest rate must be in its fraction or decimal form.
Exp. If the interest rate was 2%
At 2% interest a CD with a 2000 principle will generate $80 of interests.
