The CFO of a consulting engineering firm is deciding between purchasing Ford Explorers andToyota 4Runners for company principals. The purchase price for the Ford Explorer will be $31,000.Annual maintenance costs for the Explorer are expected to be $600 per year more than that of the4Runner. The purchase price for Toyota 4Runners is 35,000 The trade-in values after 3 years areestimated to be 50% of the first cost for the Explorer and 60% for the 4Runner.(a)What is the incremental ROR between the two vehicles?(b) Provided the firm’s MARR is 18% per year, which vehicle should it buy?

See the story of Larry Walters, Lawn Chair Pilot at the end of this HW assignment. If Larry used 42 helium-filled balloons with a 4 ft. diameter, would this story be plausible? a. Assume a reasonable weight for a) Larry (~170 lbs), b) the chair (~10 lbs), c) the balloon materials (about 4 lbs each when empty), d) accessories (beer, food, CB radio, etc. -~20 lbs total), and e) water jugs he used for ballast (assume 8 gallons of water). b. Assume a typical density for air from the tables in the textbook (don't be concerned with the exact elevation he reached, just whether he could get off the ground). C. Yhelium 0.01 lb/ft³. = The balloons he used actually had an ft. diameter (not 4 ft). How does that fact change your calculations?
Suppose you have a track dozer that is a 325 fwhp diesel powered machine and it is expected to be operating at an average of 85% power and at a 48-minute hour efficiency.And suppose the cost of off-road diesel is $3.00 per gallon. Using the approximate consumption rate of 0.04 gallon per fwhp-hr, how much is the fuel expense for this track dozer per hour?

A load of 50 rolls of R-11 insulation must be picked up. Each roll is 25 inchesin diameter and 15 inches tall. What is the smallest volume a closed-backtruck could hold to be able to pick these rolls up in one load? (In reality, alarger volume is needed since the truck is rectangular and the rolls arecylindrical.) Round the answer to the next higher whole cubic foot.
Engineers determined that a small amount of newly available chemical additives would increase the resistance of a building material by 20%. The factory manager arranged the purchase of the additive through a 5-year contract at a price of $7,000 annually, with an interest of 15% to be installed annually, and an inflation of 10%, starting from one year from now. The annual price is expected to increase by $50 annually starting from the sixth year and thereafter until the year 13. In addition, an initial investment of $3,000 has been made to prepare a suitable site for the contractor to deliver the additive. Find the equivalent total present value of all these cash flows.
