Nihar got a good grade at school, so I gave him \({N}\) two dollar bills. Then, since PiHan got a better grade, I gave him just enough five dollar bills so that he got more money than Nihar. Finally, since Calvin got the best grade, I gave him just enough ten dollar bills so that he got more money than PiHan. What is the maximum amount of money (in terms of \(N\)) that Calvin could have received?

\(N\) is a positive integer.
