Answer:
(C) Decrease No effect
Step-by-step explanation:
at purchase:
30,000 shares x 16 dollars each:
Treasury stock 480,000 debit
Cash 480,000 credit
--purchase of own share--
Then we will decrease retained earnings for the difference in the cash proceed on the sale and our treasury stock.
30,000 x 12 dollars = 360,000 cash proceeds
treasury stock 480,000
decrease in RE 120,000
cash 360,000 debit
retained earnings 120,000 debit
Treasury Stock 480,000 credit
