Start with the given formula:



Then plug in the values we know:





Take the root (forget about the negative root, we certainly aren't looking for a negative interest rate):





The arithmetic is yours to do. Ask your teacher/instructor/professor where to get this interest rate. Wow, I want a piece of that!
