In January 2020, Marketplace Retail started a promotional campaign for the sale of its Sanicare 18-roll pack toilet tissue with a sales price of P400 per pack. A coupon is attached to each pack and customers can avail of a 200-ml. Dovey body wash upon presentation of 5 coupons. Each 200-ml. Dovey body wash costs P180 and sells for P250. During the year 2020, 5,000 packs of 18- roll toilet tissue were sold and Marketplace Retail estimates at only 60% of the coupons in the hands of consumers will be presented for redemption. As of the end of the year, 400 bottles of 200 ml. Dovey body wash were redeemed. How much is the unearned revenue from unredeemed premiums on December 31, 2020?
