A county will invest $3,600,000 to clean up a chemical spill that occurred following a natural disaster. At the end of the 9-year planni horizon, an additional $900,000 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 estimat be $2,400,000.

Transcribed Image Text:A county will invest $3,600,000 to clean up a chemical spill that occurred following a natural disaster. At the end of the 9-year planning
horizon, an additional $900,000 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 $2,400,000. Determine the B/C ratio for the investment using a 5% MARR.

B/C=
Carry all interim calculations to 5 decimal places and then round your final answer to 3 decimal places. The tolerance is ±0.003.

Transcribed Image Text:The benefit-cost ratio (B/C) is the ratio of the present worth of net public benefits to the present worth of net government costs
using i = MARR.
To illustrate the mathematics of benefit-cost analysis:

The B/C criterion may be expressed mathematically, using the present worth of all net benefits over the present worth of all net
costs, as
