Question

You have $1000 you want to save, but you don’t want to put it into a savings account the pays only 0.5% per year. Instead, you have decided to put your money into a CD that pays simple interest for three months. At the end of the three months (1/4 of a year) you get your money and interest back. The interest rate you were able to get was 3% per year. What is the total amount of interest (ie. extra money you get) that was earned on this CD?

Answer 1

$30

Explanation:

If the CD paid back 3% interest of the money you put in, all you have to find is what 3% of $1000 is.

3% = 0.03.

0.03 x 1000 is $30.

You earned $30 in interest.
