Answer and Explanation:
The journal entry is shown below:
Cash Dr (1,000 × $65) $65,000 Â
   To Sales revenue $59,000 Â
   To Deferred Revenue -Discount coupon  $6,000
(1,000 × $100 × 30% × 20%)
(Being the sales revenue is recorded)
here the cash is debited as it increased the assets and credited the sales revenue and deferred revenue as it increased the revenue and liabilities
