Wynn Corp. offers a set of building blocks to customers who send in three codes from Wynn cereal, along with $1. Wynn purchased 100,000 building block sets in 2020 for $2.50 each, and paid for them by cash. During 2020, Wynn sold one million boxes of cereal for $4 per box. Wynn estimates that 10% of the sales amount received from customers relates to the building block sets to be awarded. Wynn expects 30% of the codes to be sent in, and in 2020, 240,000 codes were redeemed. Prepare all necessary journal entries for 2020 if
