Calculate the modified B/C ratio (use AW) at a discount rate of 10% APR, compounded daily. b. Is the project justified? O A. No, the B/C ratio is > 1 O B. Yes, the B/C ratio > 1 Please calculate your dollar values to the nearest whole dollar. Format 0000 No commas. c.

What is the breakeven value of statistical Me (VSL) needed to justify a highway project if i is 8%? The death rate on a particular three-lane road is 8 per 100 million vehicle-miles. Adding a lane would reduce this to 5 per million, and other accidents would cost $1.5M per mile to build, and annual maintenance would be 3% of the first cost. Assume that the lane would last 40 years. The road carries 10000 vehicle per day. Use reduction factor of 3/8 for all accidents. (Non-CE students no need to answer this item).

NO EXCEL An engineer is trying to decide which process to use to reduce sludge volume prior to disposal. Belt filter presses (BFP) will cost $200,000 to buy and $80,000 per year to operate. Belts will be replaced one time per year at a cost of $5,500. Centrifuges will cost $400,000 to buy and $120,000 per year to operate, but because the centrifuge will produce a thicker cake, the sludge hauling cost to the monofill will be $30,000 per year less than for the belt presses. The useful lives are 5 and 10 years for BFP and the Centrifuge respectively. The salvage values are assumed to be 10% of the first cost of each process whenever they are closed down or replaced. The interest rate is 8%. Use the PW method to select the more economical process.Using an Engineering Economics Formula
