An engineer launches a project in the country's top technohub. This involves rental of a computer unit for online class students. He felt that because of the density of students in the area, 90% of his 30-units will be occupied per sem (5 months each) per year. He desires a rate of return of 20%. Other pertinent data are the following:
Assess the project using (1) ROR, (2) Present Worth Method, and (3) Future Worth Method. (4) Estimate the payback period of this project.
