Design changes are identified to be one of the major causes of project delays and cost overruns. As a construction project manager, what would you do to avoid or minimize the impact of this problem?

Write a pseudocode for the following code:

/*every item has a name and a cost */
public class Item {

   private String name;
   private double cost;
   public Item(String name, double cost) {
       this.name = name;
       this.cost = cost;
   }
   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public double getCost() {
       return cost;
   }
   public void setCost(double cost) {
       this.cost = cost;
   }   
}

public enum PaymentType {
   CASH,
   DEBIT_CARD,
   CREDIT_CARD,
   CHECK
}

/*every payment has a type and an amount*/

public class Payment {
   private double amount;
   private PaymentType paymentType;
   public Payment(double amount, PaymentType paymentType) {
       this.amount = amount;
       this.paymentType = paymentType;
   }
   public double getAmount() {
       return amount;
   }
   public void setAmount(double amount) {
       this.amount = amount;
   }
   public PaymentType getPaymentType() {
       return paymentType;
   }
   public void setPaymentType(PaymentType paymentType) {
       this.paymentType = paymentType;
   }   

The table below represents the output and cost structure for a firm. The market is perfectly​ competitive, and the market price is ​$10. Total costs include all implicit opportunity costs.

1. Calculate the firm’s profit at each rate of output and fill in the values in the table.
2. Calculate firm's marginal cost and marginal revenue at each rate of output and fill in the values in the table.
3. Calculate the firm’s average total costs and average variable costs at each rate of output and fill in the values in the table.
4. Based on the information in the table​ above, plot marginal cost​ (MC) at each rate of output. Properly label this line.
5. ​Based on the information in the table​ above, plot marginal revenue​ (MR) at each rate of output. Properly label each line.
6. Based on the information in the table​ above, plot average total costs ​ (ATC) and average variable costs at each rate of output. Properly label each line.
7. Highlight in yellow the short-run supply curve for this perfectly competitive firm.
8. Based on marginal​ analysis, what is the​ profit-maximizing rate of output for the firm?

You want to invest in a project in Greenland. The project has an initial cost of G$776,000 and is expected to produce cash inflows of G$397,000 a year for three years. The project will be worthless after three years. The expected inflation rate in Greenland is 4.2 percent while it is 1.2 percent in the U.S. The applicable interest rate in Greenland is 5.87 percent. The current spot rate is G$1 = US$.12. What is the net present value of this project in U.S. dollars using the foreign currency approach? (Find the NPV in G$, then convert to US$ using the spot rate)

$30,209.87

$38,357.72

$36,428.66

$34,529.20

$32,547.36

Suppose the spot price of a bushel of wheat is $2.00, the annual storage cost is $0.30 per/bushel, the risk‐free rate is 8%, and the costs of transporting wheat from the destination point specified on the futures contract to a local grain elevator, or vice versa, is $0.01/bu.

a. Use the cost‐of‐carry model to determine the equilibrium price of a September wheat futures contract (expiration of T = 0.25).

b. Explain the arbitrage strategy an arbitrageur would pursue if the September wheat contract is trading at $2.16/bu.

Environmental costing is an attempt to take the explicit and implicit environmental cost associated with a product into account during the production process. Required: Based on your own research on Environmental Costing, discuss what you have learned about it. You may share examples, provide definitions, or anything else relevant to the topic.

Need an academic response to this post of a student

I know that the opportunity cost for getting my degree will pay off. the reason behind this is I see many companies I want to work for are wanting bachelor's degrees. I do think it is smart to make sure you can obtain work experience in the field before you get your degree to make it an easier transition. I also think people need to analyze what the degree is in and is there a future for it. Also looking at is it a good idea to pick a degree in the area I live in. Certain degrees are not as in demand as other jobs in certain areas. Many people also get into a lot of debt for careers that will not pay well. so they struggle to stay afloat with that debt on their head. I think it is important to look at your situation I look at how I have a husband who works and as do I. This helps me be able to survive and still go to school.

This is the topic discussion

Define the opportunity cost of getting your degree by analyzing what steps and economic factors a potential student must make when choosing to pursue an education. Given your answer, is getting a formal college education worth your opportunity costs? Why?

Consider the new Starbucks in Bethlehem. Suppose the wage is w = $9, and the cost of capital is r = $1, and their production function for cups of coffee is q = 4K^0.5L^0.5

a) What is the least/minimum cost of inputs combination required to produce 120 cups of coffee?

b) What would be the total cost of producing 120 cups of coffee?

c) Suppose instead that capital was fixed at 25 units. What would be the implications for labor usage maintaining q = 120?

d) Keeping capital fixed at 25 units. What would be the implications for total cost maintaining q = 120?

What arguments can be given that the historical cost framework should be abandoned?
