The conventional B/C ratio estimate of 2.1 was reported to the County Commissioners for a proposed mosquito control program.The person who prepared the report stated that the health benefits were estimated to be $400,000 per year, and that disbenefits of $25,000 per year were used in the calculation. She also stated that the costs for chemicals, machinery, maintenance, and labor were estimated at $150,000 per year. However, sheforgot to list the cost for initiating the program (trucks, pumps, tanks, etc.). If the project has a 10-year study period and an 8%-per-year discount rate, determine the estimated initial cost.

The estimated annual cash flows for a proposed municipal government project are costs of $750,000 per year, benefits of $950,000 per year, and disbenefits of $200,000 per year. Calculate the conventional B/C ratio at an interest rate of 10% per year, and determine if it is economically justified. The B/C ratio is The project is economically justified

a. Based on PW method, Design Z is more economical. b. The modified B/C ratio of Design Y is The modified B/C ration of Design Z is (Round to two decimal places) (Round to two decimal places) c. The incremental B/C ratio is (Round to two decimal places) Therefore, based on the B/C ratio method, Design Z is more economical d. The discounted payback period of Design Y is The discounted payback period of Design Z is years (Round to one decimal place) years (Round to one decimal place) Investment cost Annual revenue Annual cost Useful life Salvage value Net PW Therefore, based on the payback period method, Design y would be preferred. (e) Why could the recommendations based on the payback period method be different from the other two methods? ⒸA. because the payback period method ignores the cash flows after the payback period O B. because the payback period gives more weight to the cash flows after the payback period C Design Y Design Z $140,000 $275,000 $57,659 $96.354 $17.618 $31,687 15…
