Answer:
C. the Phillips curve is vertical
Explanation:
Philips Curve shows the inverse relationship between inflation rate & unemployment level. High inflation rate implies low unemployment rate; and low inflation rate implies high inflation rates. Economic growth (output rise) leads to inflation & reduces unemployment ; Economic slowdown (output fall) leads to deflation & increases  unemployment.  
However; In long run, real GDP (output level) returns to its potential level. So; output level defining the inverse relationship (trade off) between inflation rate & unemployment level, is stable. Hence, inflation rate & unemployment level have no inverse (trade off) relationship & they are unrelated. Therefore, the long run Phillips curve is vertical.

<span>The most probable thing that will happen if the pie maker keeps making additional pies is this: the marginal costs will continue to rise, increasing the total cost, while the marginal revenue remains the same, decreasing the profit. This is to assume that no buyer is interested in purchasing the pies at a certain period of time. </span>
        
                    
             
        
        
        
Answer:
The total surplus from Andrew's sale to Nick is $35. 
Explanation:
The total surplus is the sum of producer surplus and consumer surplus. 
The consumer surplus is the difference between the maximum price a consumer is willing to pay for a product and the price he/she actually has to pay. 
While producer surplus is the difference between the minimum price a producer is willing to accept for a product and the price he/she actually gets. 
Consumer surplus for Nick
= $80 - $60
= $20
Producer surplus for Andrew
= $60 - $45
= $15
Total surplus from generated from Andrew's sale to Nick
= $20 + $15
= $35
