10. 7.15 A project to extend canals for vegetable crop irrigation into an area that was recently cleared of Mesquite trees (a nuisance tree in Texas) and large weeds is projected to have a capital cost of

$2,000,000. Annual maintenance and operation costs will be $100,000 per year. Annual favorable consequences to the general public of

$820,000 per year will be offset to some extent by annual adverse consequences of $400,000 to a portion of the general public. If the project is assumed to have a 20-year life, what is the conventional B/C ratio at an interest rate of 8% per year?
