The B/C ratio for a mosquito control program pro- posed by the Harris County Department of Health is reported as 2.3. The person who prepared the report stated that the health benefits were estimated at $500,000, and that disbenefits of $45,000 per year were used in the calculation. He also stated that the costs for chemicals, machinery, maintenance, and labor were estimated at $150,000 per year, but he forgot to list the cost for initiating the program (trucks, pumps, tanks, etc.). If the initial cost was amortized over a 10-year period at 7% per year, what is the estimated initial cost?
