Please help me find a solution to this problem, I am having problems calculating the price/earnings ratio.

McDaniel Corporation had net income for 2016 of $81 ,000. McDaniel had 7,000 shares of common stock outstanding at the beginning of the year and 19,000 shares of common stock outstanding at the end of the year. There were 12,000 shares of preferred stock outstanding all year. During 2016, McDaniel declared and paid preferred dividends of $16,000. On December 31 , 2106, the market price of McDaniel's common stock is $49 per share and the market price of its preferred stock is $72 per share. What is McDaniel's price/earnings ratio?
