Jack owns a local trucking company. With fuel costs being expensive, Jack wants to evaluate how much fuel, on average, he should store in his 9,000 gallon fuel tank. Each year Jack uses 90,000 gallons of diesel (usage is spread evenly throughout the year). Jack knows with certainly that he can have a load of fuel delivered in 5 days. The price of fuel is $3.09 per gallon and there is a separate $120 ordering fee per order. Jack thinks his holding cost per unit is 30%. If Jack orders at EOQ, what will be the average inventory of fuel in his 9,000 gallon tank?

A. ≈1,206 gallons

B. ≈2,578 gallons

C. ≈2,413 gallons

D. ≈2,290 gallons

Suppose that a major city’s main thoroughfare, which is also an interstate highway, will be completely closed to traffic for two years, from january 2014 to december 2015, for reconstruction at a cost of $535 million. if the construction company were to keep the highway open for traffic during construction, the highway reconstruction project would take much longer and be more expensive. suppose that construction would take four years if the highway were kept open, at a total cost of $800 million. the state department of transportation had to make its decision in 2014, one year before the start of construction (so that the first payment was one year away). so the department of transportation had the following choices: (i) close the highway during construction, at an annual cost of $267.5 million per year for two years. (ii) keep the highway open during construction, at an annual cost of $200 million per year for four years. now suppose the interest rate is 80%. calculate the present value of the costs incurred under each plan.
