An alternative has the following cash flows: benefits = $50,000 per year; disbenefits = $27,000 per year costs = $25,000 per year. The B/C ratio is closed to: 0.92 0.96 1.04 2.00 The first cost of grading and spreading gravel on a short rural road is expected to be $700,000. The road will have to be maintained at a cost of $25,000 per year.

This improved accessibility has increased the property values along the road from $400,000 to $600,000. The conventional B/C ratio at an interest rate of 6% per year for a 10-year study period is closest to: 1.3 1.7 1.9 2.1 2.8
