Answer:
On average the firm issued shares at $15 dollars each
Explanation:
the treasury stock are purchased at the market price which is not the same as the issuance price thus, we ignore it.
the company issued 33,600 shares with par value of $10
from which it has $168,000 additional paid-in
In total: 33,600 x $10 = 336,000
+ 168,000
Total paid-in 504,000
504,000 / 33,600 = $15
