Hi Lauren,
It looks like your Professor has a mistake in the number of shares after Houghton reacquired some of its stock.
It should read, (200,000 × $25) = 5,000,000.
Then, when it resells 100,000 shares at $30 share, that should read, (100,000 × $30) = 3,000,000.
To balance this, you account for 100,000 shares at the original value of $25 and the additional paid-in capital of $5 for those 100,000 shares.
(100,000 x $25) = 2,500,000 and (100,000 x $5) = 500,000
Does this help?
