Five years ago, Debbie purchased 1,000 shares of common stock in Jones Corporation for $21,000. In the current year, Debbie receives a nontaxable stock dividend of 50 shares of Jones preferred. Total values at the time of the dividend are: $50,000 for the preferred and $100,000 for the common. Based on this information, what is Debbie's basis?

I need answer ASAP, please.
