Clarks Inc., a shoe retailer, sells boots in different styles. In early November the company starts selling SunBoots to customers for $60 per pair. When a customer purchases a pair of SunBoots, Clarks also gives the customer a 20% discount coupon for any additional future purchases made in the next 30 days. Customers cant obtain the discount coupon otherwise. Clarks anticipates that approximately 10% of customers will utilize the coupon, and that on average those customers will purchase additional goods that normally sell for $130. Required: 1. How many performance obligations are in a contract to buy a pair of SunBoots? 2. Prepare a journal entry to record revenue for the sale of 1,500 pairs of SunBoots, assuming that Clarks uses the residual method to estimate the stand-alone selling price of SunBoots sold without the discount coupon.
