Answer:
Sarah would have $ 1725 at the end of the year.
Explanation:
If Sarah opens a savings account that has a yearly simple interest rate of 15%, and deposits $1500, she would have at the end of the year:
- the capital invested ($ 1500)
- plus the interests earned that consist of a 15% of $ 1500 = $225
In total she would have $ 1500 + $ 250 = $ 1725.
Another way to calculate this amount of money is the following:
$ 1500 . 1.15 = $ 1725
In other words:
$ 1500 = 100% of $ 1500 = 100% . $ 1500
$ 225 = 25% of $ 1500 = 25% . $ 1500
$ 1500 + $ 225 = 100% . $ 1500 + 25% . $ 1500 = (100% + 25%) . $ 1500 = 125% . $1500 = 1.25 . $ 1500 = $ 1725
