The company was purchased by an investment firm called American industrial partners (AIP) that has so far earned only a 1 percent return on its investment. Obviously the company is having problems. Its sales are up but earnings are down. In the first three months after acquisition, the company lost $2 million on $68 million in sales.

The plant is hot and dirty and crumbling, and they are working harder to produce items of poorer quality. Fewer than 7 of 10 orders are shipped on time, and 2% of sales are returned as defective. Built in 1924, the plant sprawls over 14 buildings, with only the offices and lunchroom air-conditioned. Equipment is…

The economy in town seems to be growing, and he is wondering whether he should opt for a subcompact, compact, or full-size pickup truck. The smaller truck would have better fuel economy, but would sacrifice capacity and some durability. A friend at the Bureau of Economic Research told him that there is a 30% chance of lower gas prices in his area this year, a 20% chance of higher gas prices, and a 50% chance that gas prices will stay roughly unchanged. Based on this information, Miles has developed a decision table that indicates the profit amount he would end up with after a year for each combination of truck and gas prices.
