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

Answer:
Instructions are listed below
Explanation:
Giving the following information:
Zortek Corp. budgets production of 380 units in January and 270 units in February. Each finished unit requires four pounds of raw material Z, which costs $3 per pound. Each month’s ending inventory of raw materials should be 50% of the following month’s budgeted production. The January 1 raw materials inventory has 190 pounds of Z.
Prouction January= 380 units*4 pounds= 1520 punds
Production Febreaury= (270*4pounds)/2= 540 pounds
Initial inventory= 190 pounds (-)
Purchase= 1870 pounds
Answer: e)5% and $80,000
Explanation:
$320,000 was generated by the salespeople in this territory.
This territory comprises 10% of a $64 million market.
Territory comprises of = 10% * 64,000,000 = $6,400,000
Their market share is therefore;
=
* 100%
= 5%
Four people made sales of $320,000.
Their productivity = 
= $80,000
Answer:
The average product of labor per day is 324
Explanation:
To find the average product of labor per day we need to know the total number of widgets produced divided by the worked days.
Average Product= total number of widgets /days
Monday, 10=250 widgets
Tuesday, 11=286 widgets
Wednesday, 13 =364 widgets
Thursday, 14 workers= 396 widgets
Friday, 12 workers=324 widgets
TOTAL WIDGETS= 250+286+364+396+324=1620
Days= 5 days
Average Product= 1620/5=324
