Think of any profit or development project, assume the different costs of the project (i.e. capital costs, operational costs or any others). Assume that the project life time is 20 years. Assume an interest rate of 5% per year. Distribute the capital costs over three phases during the project life time. Assume the amount of production as well. Assume the unit price for the consumers.

1- Calculate the total annual project costs? 

2- Calculate and draw the cash flow of the project? 

3- Calculate the average unit cost? 

4- Calculate the Present value of the project costs? 

5- Calculate the recovery period?
