Many of Exercises 29-40 are similar or identical to ones in preceding exercise sets. Use duality to answer them.
Purchasing The Enormous State University’s Business School is buying computers. The school has two models to choose from, the Pomegranate and the iZac. Each Pomegranate come with 400 GB of memory and 80 TB of disk space, while each iZac has 300 GB of memory and 100 TB of disk space. For reason related to its accreditation the school would like to be able to say that it has a total of at least 48,000 GB of memory and at least 12,800 TB of disk space. If both the Pomegranate and the iZac cost $2,000 each, how many of each should the school buy to keep the cost as low as possible? What are the shadow costs of memory and disk space?

The garden and a walkway around its perimeter have an area of 690 square feet. Find the width of the walkway (x) if the garden measures 14 feet wide by 18 feet long. Write answer to 2 decimal places. (Write the number without units). Hint: add 2x to each of the garden dimensions of 14 x 18 feet to get the total area for the length multiplied by width.arrow_forward
