Consider this situation faced by a first-semester senior in civil engineering who is exhausted from extensive job interviewing and penniless from excessive partying. Mary’s impulse is to accept immediately a highly attractive job offer to work in her brother’s successful manufacturing company. She would then be able to relax for a year or two, save some money, and then return to college to complete her senior year and graduate. Mary is cautious about this impulsive desire, because it may lead to no college degree at all!

Your company has invested $5 million in developing a new product, but the development process isn’t quite complete. You have just learned from your marketing team that other companies have introduced similar products. As a result of this competition, the expected sales of your new product once you have completed development and actually begun production is now just $3 million. Your production team tells you that it will cost another $1 million to finish development and make your product. The decision is now yours: should you give the go-ahead to complete development of the product? Why or why not? In the event that your production team’s cost estimate is inaccurate, what is the most that your company should pay to complete development? Why? Be sure to incorporate (and define) the relevant concept into your answer.

- Assume you are pursuing a bachelor’s degree and you have 40 hours to divide between work and school in a week. You choose the amount of time you spend on each based on the classes you take and the hours you request at work. The degree will take you 3 years to complete if you dedicate 40 hours a week and do not take summers off. Obviously, if you devote no time to school, you never get your degree. You have been going to school full time for two quarters. In the third quarter, you do not receive as much loan money as you anticipate and need. You decide to work 20 hours a week to make up the difference and take fewer classes. What is your opportunity cost?

- The buyer of a piece of real estate is often given the option of buying down the loan. This option gives the buyer a choice of loan terms in which various combinations of interest rates and discount points are offered. The choice of how many points and what rate is optimal is often a matter of how long the buyer intends to keep the property. Darrell Frye is planning to buy an office building at a cost of $988,000. He must pay 10% down and has a choice of financing terms. He can select from a 7% 30-year loan and pay 4 discount points, a 7.25% 30-year loan and pay 3 discount points, or a 7.5% 30-year loan and pay 2 discount points. Darrell expects to hold the building for four years and then sell it. Except for the three rate and discount point combinations, all other costs of purchasing and selling are fixed and identical. 1. If Darrell chooses the 2-point 7.5% loan, what will be his total outlay in points and payment after 48months?

Coyote has placed an order for 30 tons of TNT from Acme Enterprises. Acme can manufacture TNT using raw materials (Z) found in a remote underground mine. Acme needs 1/3 ton of Z to produce 1 ton of TNT and they are deciding where to locate their factory in order to minimize transportation costs. The mine and Wile E. Coyote's house are 50 miles apart. By train, the cost of shipping 1 ton of both TNT and Z is $2 per mile. However, Acme faces an additional cost because a river passes between the mine and Wile E. Coyote's house, and the river has no bridge. Wile E. Coyote's House River Mine Both Z and TNT must be loaded onto barges to cross the river, which is located 16 miles from the mine. Barge operators charge $1 per ton of TNT shipped across the river.
