Answer:
b. $290,000
Explanation:
The computation of the cash flows from operating activities to be reported on the statement of cash flows is shown below:
= Net income reported on the income statement + decrease in account receivable 
where,
Net income reported = $280,000
And, the decrease in account receivable is $10,000 ($70,000 - $80,000)
So, the cash flow from operating activities 
= $280,000 + $10,000
= $290,000
The decrease in account receivable implies that more cash is come so it would be added and the same is shown above 
 
        
             
        
        
        
Answer:c. 12.0%
Explanation:Return on Investment (ROI) is a measure used by firms in order to determine how effective an investment is in terms of gains from its proceeds when compared to the amount invested .
 Given 
Yellowday Energy margin as 3%
turnover= 4.0 and sales as $50million, 
we can calculate the ROI,Return on Investment , as the Profit margin multiplied by turnover 
ROI = Profit Margin  x Turnover
   = 3% x 4.0
     = 0.03 x  4.0
      =0.12 
0.12 x 100 
= 12.0%

Answer and Explanation:
The computation is shown below:
TC = 25 + q^2
Now 
Marginal cost is 
= dtc ÷ dQ 
= 2q
Average variable cost  (AVC) = q
We Assuming perfect competition so there is a free entry so no profits 
Therefore 
ATC = P
ATC = TC ÷ q  
= q + 25 ÷ q
Now 
MC = MR = P = ATC
2q = q + 25 ÷ q
q = 25 ÷ q
q^2 = 25
So, Quantity per firm = q = 5
Now 
P = MC = MR = ATC 
= q + 25 ÷ q  
= 5 + 25 ÷ 5  
= 5 + 5
= 10
hence, equilibrium price is 10
Now 
Q = 35 - P  
= 35 – 10
= 25
Hence, Market quantity (Q)  = 25
And, the number of firms i.e n 
N = Q ÷ q  
= 25 ÷ 5
= 5
 
        
             
        
        
        
Answer: The correct answer is "4. when a third party is injured by an economic activity".
Explanation: A negative externality is when a third party is injured by an economic activity.
Negative externality refers to all kinds of harmful effects on society, generated by production or consumption activities, which are not present in its costs. Negative externalities occur when the action taken in our activities as a company, individual or family causes harmful side effects to third parties. Such effects are not incorporated in all costs. Since the highlighted negative effects are not present in the price of production or of the profit when consuming.
