Answer: $18,000
Explanation:
Given that,
Began 2018 with a Normal balance = $5,000
Ended 2018 with a normal balance = $11,000
Unearned Revenue account was credited = $24,000
Revenue earned by professor in 2018 : 
= Beginning unearned revenue + Advance payments - Ending unearned revenue 
= $5,000 + $24,000 - $11,000
= $18,000
Therefore, $18,000 revenue earned by professor in 2018.
 
        
             
        
        
        
Answer:
$500 short-term capital gain
Explanation:
Henrietta's gain = selling price - stock's basis = $13,500 - $13,000 = $500
Since Henrietta received the stocks on June 1, 2015, and sold them on January 1, 2016, only 7 months had passed, therefore, this transaction would be considered a short term capital gain. 
When a gift is sold (in this case the stocks), a taxpayer can use the basis for computing gains. If the stocks were sold at a loss, Henrietta should use the lower value (at the moment of the gift) to determine her loss.
