Sky Communcations (SKY) usually sells a cell phone for $320 plus 12 months of cellular service for $480. SKY has a special, time-limited offer in which it gives the phone for free and sells the 12 months of cellular service for $420. Each phone costs SKY $120, which it accounts for in its perpetual inventory system. On July 1, SKY sells one of the special packages, delivers the phone, collects the $420 cash, and starts the cellular service. 

Required:

1. For the special offer, how much of the $420 relates to the sale of the cell phone versus the sale of the cellular service?

2. What journal entries would SKY record on July 1 and July 31?
