Answer:
e. If a firm increases its sales while holding its accounts receivable constant, then, other things held constant, its days' sales outstanding will decline.
Explanation:
Days sales outstanding = Account receivables / Sales * 365
So, as Sales increases which is the denominator, and there is accounts receivable which is constant and is the numerator, then sales days outstanding will decline.
Meaning that, the higher the Sales increases while Account receivable remain constant, the sales days outstanding will continue to decline.
