Cash management system: Neon Light Company of Kansas City

Can you help me with this assignment?

Neon Light Company of Kansas City ships lamps and lighting appliances throughout the country. Ms. Neon has determined that through the establishment of local collection centers around the country, she can speed up the collection of payments by one and one-half days. Furthermore, the cash management department of her bank has indicated to her that she can defer her payments on her accounts by one-half day without offending suppliers. The bank has a remote disbursement center in Florida.

(b) If Neon Light Company can earn 9 percent per annum on freed-up funds, how much will the income be?
