the journal entry to record the sale of 100,000 Protab packages: 
 Dr Cash 88,000,000 
 Cr Sales revenue 82,500,000 
 Cr Deferred revenue - discount option 4,338,000 
 Cr Deferred revenue - extended warranty 1,162,000 
 
Explanation: 
 some information was missing, so I looked for similar questions:
 Each Protab package costs $880 
stand alone selling price of a Protab is $855 
stand alone price of Probook coupon = ($750 x 30%) x 20% = $45 
 stand alone price of extended warranty coupon = ($80 - $40) x 30% = $12 
 item stand alone prices % of package price allocation of 
 transaction $ 
 Protab $855 93.75% $825.00 
 Probook coupon $45 4.93% $43.38 
 Ext. warranty coup. $12 1.32% $11.62 
 total $912 100% $880.00
