To find the interest Dakota will earn in 3 years, we use the simple interest formula:

\[
i = prt
\]

where:
- $ p = 70000 $ (the principal amount),
- $ r = 0.06 $ (the interest rate as a decimal),
- $ t = 3 $ (the time in years).

Substitute the values into the formula:

\[
i = 70000 \times 0.06 \times 3
\]

Calculating step-by-step:

1. $ 70000 \times 0.06 = 4200 $
2. $ 4200 \times 3 = 12600 $

So, Dakota will earn **$12,600** in interest over 3 years.

Here are some related questions you might explore:
1. What would the interest be if the rate were 8% instead of 6%?
2. How would the interest change if Dakota invested for 5 years instead of 3?
3. What would happen if the interest were compounded annually instead of calculated as simple interest?
4. How does simple interest differ from compound interest in terms of long-term growth?
5. How can Dakota increase her earnings without increasing the principal?

**Tip:** Simple interest is always calculated on the initial principal, while compound interest calculates on the growing balance, including interest from previous periods.

Dakota has $70,000 in a savings account. The interest rate is 6% per year and is not compounded. How much interest will she earn in 3 years?

Learn how to calculate simple interest for a savings of $70,000 at an interest rate of 6% over a period of 3 years. This problem uses the formula i = prt and is suitable for middle school students learning about basic interest calculations.
