Problem 1. It is proposed to build a bridge over an intersection to reduce the traffic jam at that intersection, which can result in time saving valued as $50K per year. The construction of this bridge costs $30K; and it requires maintenance with the cost of $20K every 5 years. On the other hand, shop owners on the intersection may lose income of $10K per year. If the bridge is expected to last for a very long time and the minimum attractive rate of return is 15% per year, use the modified B/C ratio method (with annual worth) to recommend the acceptance or rejection of this project Problem 1.
