An electronics firm manufactures two types of personal computers
(PC), a desktop model and a laptop model. The production of a
desktop computer requires a capital expenditure of $400 and 40
hours of labor. The production of a laptop computer requires a
capital expenditure of $250 and 30 hours of labor. The firm has
$20,000 capital and 2,160 labor-hours available for production of
desktop and laptop computers. Each desktop computer contributes a
profit of $320 and each laptop computer contributes...

2. A computer hardware firm sells both laptop computers and
printers. It has a large inventory of laptops and printers that it
wants to sell, so it has no variableproduction cost. Through the magic of focus groups, their pricing
team determines that they have an equal number of three types of
customers, and that these customers’ reservation prices are shown
in the table:LaptopPrinterBundleCustomer A$800$100$900Customer B$1000$50$1050Customer C$600$150$750a. If the firm were to charge only individual prices (not use

served, Starbucks management configures the store offerings to take
maximum advantage of the space available and customer
preferences.
Starbucks’ actual distribution
system is much more complex, but for the purpose of our exercise
let’s focus on a...

A computer manufacturer produces three types of computers:
laptop, desktop, and tablet The manufacturer has designed their
supply chain in such a way so that the final assembly of their
computers entails putting together different quantities of the same
parts. We will assume that the costs for parts unique to the model
have already been accounted for in the reported per-unit profits,
and that inventory levels for these other parts do not change the
optimal allocation. We assume that there...
