3. Atlantic Megaprojects him a contract to build a tunnel connecting two Atlantic provinces. The tunnel should be completed in three years and requires a total investment of $220,000: $80,000 during the rst year and $70,000 during each of the second and third year. If they wish, Atlantic Megaprojects could complete the project in two years by subcontracting part of its work. In this case the required investment would be $115,000 during each of the rst and the second year. In either case, the government would pay to Atlantic Megaprojects a total of $350,000: $150,000 one year aer the project is completed and S 200,000 two years after the project is completed. The opportunity cost of capital for the company is 15%. (a) For each of the two cases, construct a table containing the cash flows and discounted cash ows. (b) Using the NPV method, decide if Atlantic Megaprojects should sub- contract, complete the project by themselves or none of the two. [Sub- oontract, NPV is larger] to) Now suppose that the cost of capital is only approximate. What is the maximum discount rate for which the project is still attractive? [IRR, 22.47%]
