15) The basic economic theory shows that the demand and price are related by the linear model. A recent survey shows that demand and price of a new computer are given by the function D = -0.21P+ 730.
D represents the demand (measured by millions) and P the price (measured by dollar).
a) Find the inverse of this function.
b) Find the price when D is $562.

It is 5.8 you add all of the up to equat 180 then solve the equation

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
