Jordan invests 600 in his savings account the interest rate is $6 per year find the simple interest rate earned in 3 years. Then

aleksklad [387]

I believe you meant that the interest rate is 6%. Interest rates are given as percents.

To find the simple interest, we just multiply the principal amount by the rate and then by the number of years.

600 x 0.06 x 3 = 108

The total amount including interest will be 708.
