Answer:
(i) Q=300
(ii) Elasticity of Demand=-3.33 (elastic)
(iii) Income Elasticity= 2.5 (normal good)
(iv) Advertising Elasticity: 1.5
Explanation:
The Demand function is given by

(1) To solve (i) we need to replace P = 200, I = 150, and A = 30 in the demand equation:

(2) To find the price elasticity (how much quantity demanded changes with price) we use the point price elasticity formula

From the above equation we get: 
Replacing in the elasticity formula

in absolute terms the elasticity is bigger than one so it is an elastic demand.
(3) For income elasticity (how much quantity demanded changes with income), we proceed similarly as above. But the derivative is respect to income
[/tex]
Which is bigger than one, denoting this is a normal good because it's bigger than one.
(4) Advertising elasticity (how much quantity demanded changes with expenditures in advertising), we proceed as before

The most suitable strategy for all parties to communicate is by using a videoconference in which allows all of the people to have a meeting and to be able to see each of the people involved in a meeting. Using a conference call may also be useful but the lacking of it is that you may not be able to see the people you're talking to. Other choices aren't suitable as this will not allow you to talk to everyone all in the same time.
