A county will invest $5,000,000 to clean up a chemical spill that occurred following a natural disaster. At the end of the 10-year planning horizon, an additional $1,000,000 will be spent in restoring the site to an environmentally acceptable condition. The investment is expected to produce net annual benefits that will decrease by 25% each year. The net annual public benefit in the 1st year is estimated to be $2,500,000. Determine the B/C ratio for the investment using a 5% MARR. Enter your answer to 2 decimal places. (Example: 3.21)
