Evelyn opened a savings account that pays 7.5% simple interest. She deposited $450.how much interest will evelyn earn after 3 yeas

How frequently is the interest compounded? If only once a year, then the account value after 3 years is

450*(1.075)^3 = $ 559.03

If it's simple interest, it just grows by 450*.075 = $33.75 per year.

To calculate the interest that Evelyn will earn after 3 years, we can use the formula for simple interest:

Interest = Principal x Rate x Time

Where:
- Principal is the initial deposit amount
- Rate is the interest rate per year
- Time is the number of years

In this case, Evelyn deposited $450 and the interest rate is 7.5% (or 0.075), and the time period is 3 years.

Let's calculate the interest:

Interest = $450 x 0.075 x 3
Interest = $33.75

Therefore, Evelyn will earn $33.75 in interest after 3 years.

To calculate the amount of interest Evelyn will earn after 3 years, you can use the formula:

Interest = Principal * Rate * Time

Where:
Principal = $450 (the initial deposit)
Rate = 7.5% (expressed as a decimal, so 7.5% becomes 0.075)
Time = 3 years

Now let's substitute the values into the formula:

Interest = $450 * 0.075 * 3

To get the answer, simply multiply the values together:

Interest = $450 * 0.075 * 3 = $101.25

Therefore, Evelyn will earn $101.25 in interest after 3 years.
