A toll road is being considered as a replacement for the current road linking Purdue and Chicago. Investment costs of the structure are estimated to be $10,500,000, and $610,000 per year in operating and maintenance costs are anticipated. In addition, the road must be resurfaced every fifth year of its 30- year projected life at a cost of $1,400,000 per occurrence (no resurfacing cost in year 30 and the initial surfacing of the road is included in the $10,500,000). Revenues generated from the toll are anticipated to be $4,000,000. Assuming zero market (salvage) value for the bridge at the end of 30 years and a MARR of 9% per year, what is the conventional B-C ratio for this project
