1) Using the following table, prepare a diagram illustrating the demand and supply curves. Properly label the diagram and include the following:

i) demand and supply curves

ii) price and quantity axes

iii) equilibrium

iv) shortage

v) surplus

Table:

Quantity Demanded Price Quantity Supplied

10 $100 50

20 $80 40

30 $60 30

40 $40 20

50 $20 10

you have $500 to spend. Choose any TWO products you would purchase with that $500 (ensure that the price per unit of the items you decide to purchase be divisible by factors of $500).

a) Draw and label the budget line illustrating the two products/services and the budget line/budget constraint.

b) Create your own scenario and show what would happen to the budget line for those same items if the price of any one of the products/services would change (the price could either increase or decrease). Show the diagram and under, explain the scenario in your own words. 

c) Create another scenario and show what would happen to the budget line if the price of the other product/service would change (the price could either increase or decrease). Show the diagram explain the scenario in your own words. 

d) Draw a diagram to illustrate what would happen if your income would increase to $1000.

e) Draw a diagram to illustrate what would happen if the income would decrease to $250.

With reference to the market for roses, and given the scenario explained in the excerpt, further assume that when the market opened up, the demand for roses increased. Explain, with the aid of a graph, the overall impact of these changes on the equilibrium price and quantity of roses.

Regression (Equation)

QSold = 8536.213882 - 835.7223514 Price + 0.592228496 Advertising

A. Estimate sales when the price is $50 and advertising is $100,000, stating any assumption that you need to make.

Mike is preparing for exams in economics and history. He has time to read 40 pages of economics and 30 pages of history.
