Answer:
the first part is missing, so I looked it up:
1) December 30, 202x, treasury stocks are purchased
Dr Treasury stocks 1,625
Cr Cash 1,625
2) Stockholders' Equity
Paid-in capital:
Retained earnings $53,000
Treasury stocks (125 stocks at cost) ($1,625)
Total Stockholders' Equity $51,375
3) outstanding shares = 310 - 125 = 185 outstanding stocks
