An experimental composite engine block for an automobile will trim 20 pounds of weight compared with a traditional cast iron engine block. It is estimated that at least $2,500 in life-cycle costs will be saved for every pound of weight reduction over the engine’s 8-year expected life. Given that the engine’s life is 8 years, what assumptions have been made to arrive at the $2,500 per pound savings? (2.1)
The assumptions that can be made to arrive at $2,500 per pound savings.
Explanation of Solution
The total mileage driven would have to be specified in addition to the variable cost of fuel per unit or dollar per gallon.
Also, the fixed cost of both engine blocks should be assumed. The efficiency of the composite engine and traditional engine should also has be mentioned.

- The price of a car you want is $36,000 today. Its price is expected to increase by $1000 each year. You now have $22,000 in an investment account, which is earning 8% per year. How many years will it be before you have enough to buy the car without borrowing any money? (Use Goal Seek to determine the time taken.) The time taken is determined to be years.arrow_forwardA manufacturer buys certain equipment form suppliers at $30 per unit. Total requirement is 200 units/ quarter.

Their daughter, Paige, is now 8 years old and will be entering college 10 years from now (t = 10). College tuition and expenses at State U. are currently $16,000 a year and are expected to increase at a rate of 4% a year. They expect Paige to graduate in 4 years (if Paige wants to go to graduate school, she's on her own). Tuition and other costs will be due at the beginning of each school year (at t = 10, 11, 12, and 13). So far, Nathan and Stephanie have built up $9,000 in the college savings account. Their long-run financial plan is to contribute $3,000 a year at the beginning of each of the next five years (at t = 0, 1, 2, 3, and 4). Then they plan to make 6 equal annual contributions at the end of each of the following 6 years (t = 5, 6, 7, 8, 9, and 10). Their investment account is expected to earn 8%. How large must the annual payments be in the subsequent 6 years (t = 5, 6, 7, 8, 9, and 10) to meet their…arrow_forward
- an engineer knows that the supplier of their set-5100 laser surface metrology system used on one of their lines superseded their 5100 model with the 5105. the new model has a net cost of $420000. adding the new 5105 model to the production line would in decrease scrap rate estimated to save 630000 in the first year. the rate of return for on the set-5105 purchase is 13% MEMD IS 15% what is the opportunity costarrow_forwardA firm is must choose to buy the GSU-3300 or the UGA-3000. Both machines make the firm’s production process more efficient which in turn increases incremental cash flows. The GSU-3300 produces incremental cash flows of $24,998.00 per year for 8 years and costs $99,590.00. The UGA-3000 produces incremental cash flows of $29,475.00 per year for 9 years and cost $126,038.00. The firm’s WACC is 8.32%. What is the equivalent annual annuity of the GSU-3300?

- ! Required information Eight years ago, Ohio Valley Trucking purchased a large- capacity dump truck for $102,000 to provide short-haul earth-moving services. The company sold it today for $45,000. Operating and maintenance costs averaged $10,200 per year. A complete overhaul at the end of year 4 costs an extra $3600. Calculate the annual cost of the truck at i = 8% per year. The annual cost of the truck is $- per year.arrow_forwardThe Ford Motor Company has re-designed its best selling truck by substituting aluminum for steel in many key body parts. This saves 600 pounds of weight and decreases gas consumption. The fuel consumption will be 27 miles per gallon (mpg), up from 24 mpg of the previous year's model. Ford will increase the sticker price of the re-designed vehicle by $470. Assume this vehicle will be driven 16,000 miles per year and its life will be 9 years. The owner's MARR is 8% per year and gasoline costs $3.02 per gallon. What is the present worth of the incremental capital outlay for the lighter truck?

- A doctor is on contract to a medium-sized oil company to provide medical services at remotely located, widely separated refineries. The doctor is considering the purchase of a private plane to reduce the total travel time between refineries. The doctor can buy a used Learjet 31A now for $1.1 million or wait for a new very light jet (VLJ) that will be available 3 years from now. The cost of the VLJ will be $2.1 million, payable when the plane is delivered in 3 years. The doctor has asked you, his friend, to determine the present worth of the VLJ so that he can decide to buy the used Learjet now or wait for the VLJ. The MARR is 15% per year and the inflation rate is projected to be 3% per year. (a) What is the present worth of the VLJ with inflation considered? (b) Which plane should he buy?arrow_forwardHandwritten only otherwise skip and dont copy from chegg do on your ownarrow_forward← An oil refinery finds that it is necessary to treat the waste liquids from a new process before discharging them into a stream. The treatment will cost $40,000 the first year, but process improvements will allow the costs to decline by $4,000 each year. As an alternative, an outside company will process the wastes for the fixed price of $20,000/year throughout the 8 year period, payable at the beginning of each year. Either way, there is no need to treat the wastes after 8 years. Use the annual worth method to determine how the wastes should be processed. The company's MARR is 13%.
