A construction firm is evaluating two value-adding projects. The first project deals with building access roads to a new terminal at the local airport. The second project is to build a parking garage on a piece of land that the hiring firm owns adjacent to the airport. If both projects are positive-NPV projects, then the firm should: select the higher NPV project because they are mutually exclusive. not enough information is given to make a decision. accept both projects because they are contingent projects. accept both projects because they are independent projects
