Answer:
(a) 0; 0
(b) $150 per hour; $16.67 per hour
(c) (b) $150 per hour; $53.57 per hour
Explanation:
(a) Number of hours = 125
Marginal cost = 0 (since service is cost less upto 200 hours)
Average cost = 0
(b) Number of hours = 225
Marginal cost = $150 per hour
Total cost = $150 × (225 - 200) 
                 = $150 × 25 
                 = $3,750
Average cost = Total cost ÷ Number of hours
                        = $3,750 ÷ 225 
                        = $16.67 per hour
(c) Number of hours = 325
Marginal cost = $150 per hour
Total cost = $150 × (325 - 200) 
                 = $150 × 125 
                 = $18,750
Average cost = Total cost ÷ Number of hours
                        = $18,750 ÷ 325 
                        = $53.57 per hour
  
        
             
        
        
        
I don’t know if the numbers are supposed to be together or not but if it’s 752,863 than the expanded notation is:
700,000 
+	50,000 
+	2,000 
+	800 
+	50 
+	3 
And if it is 752; 863 than the expanded notation is:
700 
+	50 
+	2 
;
800 
+	60 
+	3 
        
             
        
        
        
Answer:
The answer is A.

Other things remaining equal, the law of demand says that the higher the price, the lower the quantity demanded and the lower the price the higher the quantity demanded.
Suppose a good is being sold at $5 and 20 quantities are being demanded, if the price increases to $6, lesser of that goods should be demanded
