The multivariate demand function below will be needed for questions 12-18.
Setting: Grapple, Inc. is a leading seller of laptop personal computers. However, they want to
become a leading tablet seller, too. Your marketing department, aided by your economics
staff, has estimated a function to help you in the quest for market leader in tablets. The
variables are defined after the function.
= 10000 – 25P, + 20P, + 30P, – 15Pdy – 35P3. – 10Pmm + 0.05A, + 0.03A – 25C

+ 0.1Y
Qg = the number of Grapple tablet computers demanded per week.
Pg = the price of each new Grapple tablet (in $).
Ph = the price of each Hewpaq tablet (in $).
Pr = the price of each Ronova tablet.
Pdx = the price to equip a tablet with Holographic digital video (in $, this is an upgrade option that
enables three dimensional graphics on a tablet. Two dimensional graphics is standard
equipment).
Psc = the price of various screen sizes (in $, a 8 inch is standard, but upgrade options are 10 inch
extra sharp, 12 inch, 12 inch extra sharp, Each also has a touch-screen option. The upgrades
get progressively more expensive as the size and capability increases).
Pnm = the price of memory chip upgrades (in $). More 2 Gigabyte (Gb) chips can be added. Of
course each added 2 Gb chip costs more. One 2 Gb chip is standard.
Y = average annual disposable income of a typical tablet purchaser (in $).
Ag = average age of a tablet purchaser (in years).
A = average annual Grapple advertising expenditure (in $).
