Answer:
202,000 shares
Step-by-step explanation:
170,000 common stocks outstanding, January 1
30,000 additional common stock issued, May 1 ⇒ 30,000 x 8/12 = 20,000
diluted shares = 12,000 (since each preferred stock is convertible to common stock, then all of them must be included as diluted stocks)
total number of shares = 170,000 +20,000 + 12,000 = 202,000 shares
