Answer:
Total Cost increase  5,253.4 unit 
Explanation:
given data 
weekly price a = $3.40 per gallon 
ramp up weekly b = 35%
ramp up weekly  upto x = $150( in hundred)
solution
we will use here the regression equation that is 
Y = a + b x    ...........................1
here Y is Total Cost and a is fixed cost and  
b is rate of variability and x is level of activity
so here put value in equation 1 we get 
Total Cost Y = 3.40 + 0.35 × ( 15,000)
Total Cost  Y = 3.40 + 5,250
Total Cost increase  5,253.4 unit 
 
        
             
        
        
        
Answer:
Mark's individual consumer surplus is $10. 
Explanation:
Mark and Rasheed are at the bookstore buying new calculators for the semester. 
Mark is willing to pay $75 and Rasheed is willing to pay $100 for a graphing calculator. 
The price for a calculator at the bookstore is $65. 
The consumer surplus is the difference between the maximum price that a consumer is willing to pay and the price he actually has to pay. 
Mark's individual consumer surplus 
= Price mark was willing to pay - Price he actually has to pay
= $75 - $65
= $10
