Help preferred and common stock dividends?

Posted at: 2014-12-05 
Preferred dividends are $30K per year once all the dividends in arrears have been paid. Everything else is common dividends.

When I get to 120,000 for 2012 I can't seem to calculate it correctly. Any who would like to share the answer with math to it for I can complete the other steps as well and see what I was doing wrong would be super appreciated!

...following annual dividends over a six-year period: 2009, $18,000; 2010, $40,000; 2011, $80,000; 2012, $120,000; 2013, $150,000; and 2014, $228,000. During the entire period ended December 31 of each year, the outstanding stock of the company was composed of 40,000 shares of cumulative, preferred 1% stock, $75 par, and 200,000 shares of common stock, $5 par.

Required:

1. Calculate the total dividends and the per-share dividends declared on each class of stock for each of the six years. There were no dividends in arrears on January 1, 2009. Summarize the data in tabular form. If required, round your answers to two decimal places. If the amount is zero, please enter "0".
