Italian car manufacturer Avanti will soon start exporting its luxury cars to the U.S. It expects to sell there 48,000 models annually. Cars will be brought to the U.S. by ship, with a cost of $ 12,000 per trip. Once in the U.S., cars will be stored, which charge $1,000 per month for each car stored there. How many ship trips should the company use per year? (Hint: First calculate the number of cars to be sold per month and...

In August 2017, a car dealer is trying to determine how many 2018 cars to order. Each car ordered in August 2017 costs $16,000. The demand for the dealer’s 2018 models has the probability distribution shown in the table below. Each car sells for $21,000. If the demand for 2018 cars exceeds the number of cars ordered in August 2017, the dealer must reorder at a cost of $18,000 per car. Excess cars can be disposed of at $13,000 per...
