Corollary Marketing's cash conversion cycle $($CCC$)$ is $-15$ days. The company historically has not carried any

inventory. It is planning to publish and sell a book on marketing techniques. This would result in a $30-$day

inventory conversion period and also reduce Corollary Marketing's payables deferral period by $5$ days.

What will the company's CCC be after this change?

Less

$10$ days

$20$ days

$25$ days

$30$ days
