Question

Your friend tells you that if you let him keep 5050 of your Pokemon cards for a month, he will give you 11 card extra when he returns your cards.
What is the annual rate of interest he is willing to pay for the borrowed cards?
Note: Even though he only keeps your cards for a month, we can still calculate an annual interest rate.

Answer 1

11×12 = 132 is the annual rate of interest

5050 cards?! Damm
