A large clothing retailer chain, Koll's, offers a sales incentive program where customers receive direct credit toward future purchases based upon the dollar amount of purchases today. For every $$50$ spent today, the customer will earn a $$6$ credit to be used at Koll's in two weeks. The credit expires $5$ days after it becomes active.$-$Not all customers will redeem the credit in the $5-$day window of time. Based upon historical trends, Koll's estimates that $35\%$ of the credits will be redeemed.

a$.$ Determine how many performance obligations are included in a sales transaction during the sales incentive program.

b$.$ Assuming that Koll's sold $$425,000$ of merchandise $($cost of $$170,000)$ during the first day of the sales incentive period and $8,500,$ $$6$ credits were given, record the journal entry$($ies$)$ to record sales revenue. Assume all sales were cash sales.

Note: Carry all decimals in calculations; round the final answer to the nearest dollar.
