Answer:
$30 million
Explanation:
The university collected $45 million for the summer semester which runs from June 1 to July 15 ( a 45 day period).
The revenue recognition principle states that revenue should only be recognized when the earning process has been substantially completed.
Therefore, the university should recognize revenue proportional to the 30 days of June = ($45 million / 45 days) x 30 days = $30 million
