# Road Improvement Proposal Benefit Minus Cost Calculation

Question
Engineers present three mutually exclusive road improvement proposals for consideration to the Budget Committee of City of Bombay. Costs, savings (due to reduced traffic police requirement), and estimated values of perceived benefits and disbenefits of the public for the three Proposals are given below

 Proposals 1 2 3 Public benefits/ year \$650,000 \$46500 \$750,000 Public dis-benefit/ year \$325,000 0 0 Initial construction cost \$20,000,000 \$16,000,000 \$X Maintenance cost/ year \$950,000 \$680,000 \$520,000 Traffic police operating cost saving/ year \$185,000 0 0

The planning period is 30 years. Salvage values are zero.

Determine

(a) the benefit minus cost for Proposal 1 if the interest rate 5%.
(b) the preferred (economically superior) Proposal if the interest rate is 4% and x = 28,000,000.
(c) the maximum value of x that would make Alternative 3 the preferred Alternative if the interest rate is 2%.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
