c.John’s gain on the sale is $16,750 which is the amount realized minus his adjusted basis (i.e., $62500 – 45,750). The gain is a long-term capital gain because John held the stock for more than a year before selling

Answer:
option (D) $50 billion.
Explanation:
Data provided in the question:
Additional investment spending = $20 billion
MPC = 0.6
Now,
Increase in aggregate demand = [1 ÷ (1 - mpc) ] × Investment
or
Increase in aggregate demand =  [1 ÷ (1 - 0.4) ] ×  $20 billion
or
Increase in aggregate demand = (1 ÷ 0.4) × $20 billion
or
Increase in aggregate demand = 2.5 × $20 billion
or
Increase in aggregate demand = $50 billion
Hence.
the correct answer is option (D) $50 billion.
 
        
             
        
        
        
Answer:
Option (b) is correct.
Explanation:
Sale value of the merchandise = $74,900
Sales tax liability = $74,900 × (7% ÷ 107%)
                          = $4,900
Sale value prior to sales tax = $74,900 - $4,900 
                                                = $70,000
Sales tax @7% on $70,000 = $4,900
Hope the above calculation will clear the concept since the question clearly mention that
Calhoun Crockery sold merchandise; the total proceeds collected, including a 7% sales tax, amounted to $74,900.
This $74,900 includes 7% tax also it means that the collected proceed is 100% + 7% = 107% 
which includes 7% tax liability.
