Hello can you please help me find the answer for this question?

You work for a company as a security professional and have been given a new server. You plan to use it to connect the company's 24 client computers to the Internet for e-mail access. Currently, not one of these computers has antivirus software installed. Your research indicates that there is a 95 percent chance these systems are without antivirus. A local vendor has offered to sell you licenses for 25 copies for $400 with the promise you will consider him for future business. Even though the company's 10 paid employees make only about $9 an hour, there's a good chance that a virus could bring down the network for an entire day. This company would like you to calculate the ALE. How will you answer?
