There are many options, depending on the commercial relationship between ISP and customer.
The ISP may simply charge a single one-time fee per IPv4. The customer may choose to bring their own IPv4 blocks as many BGP customers do. The ISP may chose not to charge separately per IPv4, as having those IPs enables them to charge $Y/month for Internet service. And so on and so forth. Furthermore IPv4 addresses do not wear out. IPs can be reused upon customer churn and excess blocks can be sold, if need be. - Jared
