Raul deposited $3000 into a bank account that earned simple interest each year. After 3.5 years, he had earned $262.50 in interest. No money was deposited into or withdrawn from the account.

What was the annual interest rate?

Ответ:

2,5% в год

Простые проценты обычно применяются к краткосрочным кредитам, обычно менее чем на один год. Простые проценты имеют линейное поведение.
