Marsha deposited $10,000 into a savings account 3 years ago. The simple interest rate is 3% how much money did Marsha earn in interest

10000 * 0.03 * 3 = _____

To calculate the interest earned on a savings account, we can use the formula:

Interest = Principal * Rate * Time

Where:
- Principal is the initial amount deposited (in this case, $10,000)
- Rate is the interest rate (in this case, 3% or 0.03)
- Time is the number of years (in this case, 3 years)

Using the formula and substituting the values, we have:

Interest = $10,000 * 0.03 * 3
= $300 * 3
= $900

Marsha earned $900 in interest on her savings account.

To calculate the amount of money Marsha earned in interest, we need to use the formula for simple interest, which is:

Interest = Principal × Rate × Time

In this case:
Principal = $10,000 (the amount Marsha deposited)
Rate = 3% (expressed as a decimal, 0.03)
Time = 3 years

Plugging these values into the formula:

Interest = $10,000 × 0.03 × 3

Multiplying those numbers:
Interest = $900

Therefore, Marsha earned $900 in interest on her $10,000 deposit over a period of 3 years.
