Problem 07.007 - Conventional B/C ratio for road improvement project The cost of grading and spreading gravel on a curvy rural road is expected to be $300,000. The road will have to be maintained at a cost of $34,000 per year. Even though the new road is not very smooth, it allows access to an area that previously could only be reached with off-road vehicles. The improved accessibility has led to a 144% increase in the property values along the road. If the previous market value of the property was $900,000, calculate the conventional B/C ratio using an interest rate of 6% per year and a 20-year study period. The conventional B/C ratio is
