Answer:
Credit Treasury Stock $20,000
Step-by-step explanation:
When the company reissued the shares, the Treasury Stock account is credited by the same price they were acquire. i.e. in this case we acquire the treasury stock at a price of $20.
Cash (1,000 * 12) 12,000
Additional Paid in Capital 8,000
Treasury Stock (1,000 * 20) 20,000
