Brown Corporation had an average days-of-sales-outstanding (DSO) period of 19 days in 2009. An analyst thinks that Brown’s DSO will decline in 2010 (because of expected improvements in the company’s collections department) to match the industry average of 15 days. Total sales (all on credit) in 2009 were $300 million, and Brown expects total sales (all on credit) to increase to $320 million in 2010. To achieve the lower DSO, the change in the average accounts receivable balance from 2009 to 2010 that must occur is closest to:

A. –$3.51 million.

B. –$2.46 million.

C. $2.46 million.

D. $3.51 million.
